We usually choose a mini-batch size greater than 1 and less than mm, because that way we make use of vectorization but not fall into the slower case of batch gradient descent.true/false
The answer is TRUE we choose between ,We usually choose a mini-batch size greater than 1 and less than mm
Why do we choose the batch gradient between 1 and mm?
You forfeit the advantages of vectorization across examples in a mini-batch if the size is 1.If the mini-batch size is m, batch gradient descent results, which must first process the entire training set before progressing.Mini batch in batch gradient:
In a variant of the gradient descent algorithm known as mini-batch gradient descent, the training dataset is divided into smaller batches that are then used to compute model error and update model coefficients. The variance of the gradient can be further reduced by implementations Mini-batch sizes are frequently determined as powers of 2, such as 16, 32, 64, 128, 256, etc. Make sure the minibatch fits in the CPU/GPU when selecting a suitable size for gradient descent. In general, selecting 32 is wise, summing the gradient over the mini-batch.
Hence to conclude the mini-batch size should be between 1 and less than 1 mm

Explanation:
Lake Superior, the largest of the Great Lakes of North America, is also the world's largest freshwater lake by surface area (~ 82,100 km2), and the third largest freshwater lake by volume (~ 12,100 km3). The monthly average precipitation in 2018 in the lake area was 2.69 inches. According to the data provided by USGS water stations, the total flow rate in all the incoming streams was found to be 356,747 ft3/s (cubic feet per second). At the same time, the lake discharges 717,258 ft3/s to its surrounding water bodies. The monthly average evaporation was 18.7 mm. The groundwater inflow was 783.33 km3 less than the groundwater outflow in this year. (Hints: (1) The average monthly data can be used to calculate the annual data; (2) Volume = Area * Height; (3) Pay special attention to the units, convert all the units to be consistent first.)
(1) With the information above, please write the water budget for Lake Superior (10 points);
(2) Please estimate the change of storage (in m3) in the year of 2018 (20 points);
(3) Please estimate the increase or decrease of water level (in mm) in the year of 2018 (10 points).
Answer:
1) V_win = 7.05 10¹⁰ m³ , 2)V_ lost = 1.8471 10¹⁰ m³, 3) h = 633.4 mm
Explanation:
In this exercise we will start by reducing all units to the SI system
h1 = 2.69 inch (2.54 10-2 m / 1 inch) = 6.8326 10⁻² m
Ф1 = 356.747 ft3 / s (1 m3 / 35.3147 ft3) = 10.1019 m³ / s
Ф2 = 717,258 ft3 / s = 20,310 m³ / s
h2 = 18.7 mm (1 m / 1000 mm) = 18.7 10⁻³ m
V_subterránea = - 783.33 10³ m,
Now let's answer the questions
1) they ask us the amount of water that reaches the lake in 2018
volume of rainwater is
V₁ = A. h t
V₁ = 82 100 106 * 6.8326 10-2 * 12
V₁ = 6.7315 10 10 m3
stream water volume in a year
V₂ = Ф₁ t
t = 1 year (365 days / year) (24 h / 1 day) (3600 s / 1h) = 3.1536 10⁷ s
V₂ = 10.1019 3.1536 10⁷
v₂ = 31,857 10⁷ m³
The total water volume is
V_win = V₁ + V₂
V_win = 6.7315 10¹⁰ + 31.857 10⁷
V_win = 7.05 10¹⁰ m³
2) let's find the amount of water lost from the lake
volume of water to surrounding bodies
V₃ = Ф₂ t
V₃ = 20.310 3.1536 10⁷
V₃ = 6.40496 10 8 m3
Volume of evaporated water
V₄ = A h₂ t
V₄ = 82 100 10⁶ 18.1 10⁻³ 12
V⁴ = 1,783 10¹⁰ m³
groundwater volume
V⁵ = 7.83.33 10³ m³
The volume of water lost is
V_lost = V₃ + V₄ + V₅
V_ lost = 6.40496 10⁸ + 1.783 10¹⁰ + 783.33 10³
V_ lost = 1.8471 10¹⁰ m³
3) the change in the height of the lake
the change in volume is
ΔV = V_ won - V_ lost
ΔV = 7.05 10¹⁰ - 1.8471 10¹⁰
ΔV = 5.20 10¹⁰ m³
the volume is
v = A h
h = V / A
h = 5.20 10¹⁰/82100 10⁶
h = 6.334 10⁻¹ m
h = 633.4 mm

when the national advisory committee for aeronautics (naca) measured the lift and drag on airfoil models in the 1930s and 1940s in their specially designed airfoil wind tunnel at the langley aeronautical laboratory, they made wings that spanned the entire test section, with the wing tips butted against the two sidewalls of the tunnel. this was done to ensure that the flow over each airfoil section of the wing was essentially two-dimensional (no wing-tip effects). such an arrangement prevented measuring the lift and drag with a force balance. instead, using a pitot tube, the naca obtained the drag by measuring the velocity distribution behind the wing in a plane perpendicular to the plane of the wing, i.e., the pitot tube, located a fixed distance downstream of the wing, traversed the height from the top to the bottom of the test section. using a control volume approach, derive a formula for the drag per unit span on the model as a function of the integral of the measured velocity distribution. for simplicity, assume incompressible flow.
The drag per unit span on the model can be calculated using a control volume approach as follows:
Drag per unit span = 1/2 * ρ * ∫VdzWhere ρ is the density of the fluid, V is the velocity of the fluid, and z is the distance from the top of the test section to the bottom. The integral can be calculated by summing up the velocity of the fluid at each point from the top to the bottom of the test section. This can be expressed as:
∫Vdz = ΣVzWhere Vz is the velocity of the fluid at each point in the test section.

[3] Question 5 5.1 Calculate the maximum tonnage required to compact a tantalum slug with a diameter of 88 mm. (3)
The maximum tonnage required for compacting the tantalum slug with a diameter of 88 mm was determined to be 907.4 kN.
Given the diameter of a tantalum slug as 88 mm, the maximum tonnage required to compact the tantalum slug is determined as follows;
Consider the cross-sectional area (A) of the tantalum slug, which is given by:
A = π/4 (d²)
A = π/4 (88 mm)²
= 6,049 mm²
Also, the maximum compressive stress (σ) required for compacting the tantalum slug is known to be 150 MPa.
Furthermore, the formula for the maximum tonnage required for compacting the tantalum slug is given as:
T = σA
Where T is the maximum tonnage and σ is the maximum compressive stress.
Finally, substituting the values, the maximum tonnage required for compacting the tantalum slug is given as:
T = σA
T = (150 MPa) (6,049 mm²)
= 907,350 N
Therefore, the maximum tonnage required to compact a tantalum slug with a diameter of 88 mm is 907,350 N or approximately 907.4 kN.

locate the centroid of the shaded area between the two curves
9514 1404 393
Answer:
(x, y) = (5.76, 1 5/7)
Explanation:
The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.
For the moment about the y-axis, we can define a differential of area as ...
dA = (y2 -y1)dx
where y2 = √(x/k2) and y1 = k1·x^3
The distance of that area from the y-axis is simply x.
So, the x-coordinate of the centroid is ...
\(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)
For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...
\(a_x=115.2\\a=20\\c_x=5.76\)
The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...
\(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)
The centroid of the shaded area is ...
(x, y) = (5.76, 1 5/7)
The device shown below contains 2 kg of water. The cylinder is allowed to fall 800 m during which the temperature of the water increases by 2.4°C. Some amount of water is added to the container and the experiment is repeated. All other values remain constant. This time the temperature of the water increases by 1.2°C. How much water was added to the container?
Answer:
m_added = 2 kg
Explanation:
From the question, we are told that the cylinder is allowed to fall 800 m in height. Thus, the potential energy will be converted into heat energy which will increase the temperature of water .
Now, let the mass of the falling cylinder be denoted by "m1" and let h be the height of fall.
Thus;
Formula for potential energy = mgh
Thus, as said earlier it's converted to heat generated. So heat generated = m1gh
Now let's calculate the heat absorbed;
heat absorbed = (m2)cΔt
Where;
ΔT is change in temperature
c is specific heat of water .
m2 is mass of water
Heat absorbed = heat generated
Thus;
(m2)cΔt = m1gh
Δt = m1gh/(m2•c)
Now, in both cases of the water and cylinder, m1, g , h and c are constant
Thus, we have;
Δt = (m1gh/m2) × 1/c
Where;
(m1gh/m2) is denoted as a constant k.
Thus;
Δt = K/m
For the first experiment, we have;
m = 2 kg
Δt = 2.4
Thus;
2.4 = K/2
Multiply both sides by 2 to get;
K = 4.8
For the second experiment, we have;
Δt = 1.2
Also,we have seen that K = 4.8
Thus;
Δt = K/m
Thus;
1.2 = 4.8/m
m = 1.2
m = 4 kg
Thus,mass added is;
m_added = 4 - 2
m_added = 2 kg

the allowable shearing stress is 15 ksi in the 1.5-in.-diameter steel rod ab and 7.7 ksi in the 1.8-in.-diameter brass rod bc. neglecting the effect of stress concentrations, determine the largest torque t that can be applied at a.
The largest torque that can be applied at point A without exceeding the allowable shear stress for either rod is T=44.99 k-in.
The largest torque that can be applied at point A can be determined by using the equation for shear stress of a shaft:
τ=T/J
where τ is the shear stress, T is the applied torque, and J is the polar second moment of inertia.
For the 1.5-in.-diameter steel rod AB:
J=(π/32)D4
where D is the diameter of the rod, so for a 1.5-in. rod, J=(π/32)(1.5)4=3.704 in4.
So, the largest torque that can be applied at point A while maintaining a shear stress of 15 ksi is T=(15 ksi)(3.704 in4)=55.56 k-in.
For the 1.8-in.-diameter brass rod BC:
J=(π/32)D4
where D is the diameter of the rod, so for a 1.8-in. rod, J=(π/32)(1.8)4=5.848 in4.
So, the largest torque that can be applied at point A while maintaining a shear stress of 7.7 ksi is T=(7.7 ksi)(5.848 in4)=44.99 k-in.
Therefore, the answer is T=44.99 k-in.

(20 points) A 1 mm diameter tube is connected to the bottom of a container filled with water to a height of 2 cm from the bottom. Air flows from the tube into the liquid and creates spherical bubbles with diameter about the diameter of the tube (1 mm). Everything is at 298 K. The tube is short but is connected to a much longer 2 m long hose that is 6 mm in diameter. The hose is connected to the gas supply. If there is no gas flow the water will leak into the tube and into the supply hose. When gas flows the water is blocked from entering the tube and bubbling starts. State all assumptions in answering the following questions. (a) What should be the minimum air flow rate and the gas supply pressure to keep the water from leaking back into the tube? (b) Is the flow in the hose laminar or turbulent? Is the flow in the tube laminar or turbulent?
Solution :
Given :
h = 2 cm
Diameter of the tube , d = 1 mm
Diameter of the hose, D = 6 mm
Between 1 and 2, by applying Bernoulli's principle, we get
As point 1 is just below the free surface of liquid, so
\($P_1=P_{atm} \text{ and} \ V_1=0$\)
\($\frac{P_{atm}}{\rho g}+\frac{v_1^2}{2g} +h = \frac{P_2}{\rho g}$\)
\($\frac{101.325}{1000 \times 9.81}+0.02 =\frac{P_2}{\rho g}$\)
\($P_2 = 111.35 \ kPa$\)
Therefore, 111.325 kPa is the gas supply pressure required to keep the water from leaking back into the tube.
Velocity at point 2,
\($V_2=\sqrt{\left(\frac{111.135}{\rho g}+0.02}\right)\times 2g$\)
= 1.617 m/s
Flow of water, \($Q_2 = A_{tube} \times V_2$\)
\($=\frac{\pi}{4} \times (10^{-3})^2 \times 1.617 $\)
\($1.2695 \times 10^{-6} \ m^3/s$\)
Minimum air flow rate,
\($Q_2 = Q_3 = A_{hose} \times V_3$\)
\($V_3 = \frac{Q_2}{\frac{\pi}{4}D^2}$\)
\($V_3 = \frac{1.2695 \times10^{-6}}{\pi\times 0.25 \times 36 \times 10^{-6}}$\)
= 0.0449 m/s
b). Reynolds number in hose,
\($Re = \frac{\rho V_3 D}{\mu} = \frac{V_3 D}{\nu}$\)
υ for water at 25 degree Celsius is \($8.9 \times 10^{-7} \ m^2/s$\)
υ for air at 25 degree Celsius is \($1.562 \times 10^{-5} \ m^2/s$\)
\($Re_{hose}=\frac{0.0449 \times 6 \times 10^{-3}}{1.562 \times 10^{-5}}$\)
= 17.25
Therefore the flow is laminar.
Reynolds number in the pipe
\($Re = \frac{V_2 d}{\nu} = \frac{1.617 \times 10^{-3}}{8.9 \times 10^{-7}}$\)
= 1816.85, which is less than 2000.
So the flow is laminar inside the tube.

The controller PB is 0.22, the range of the controller pressure is between 3 to 13 psig, the controller setpoint is at 72°F, and the output pressure at that temperature is 3 psig while the controller output pressure at 76°F is 6 psig
What is Controller SystemsA controller system is a type of feedback system used to regulate the performance of an output device by comparing the output to a desired set point. It uses the difference between the two values (error) to continuously adjust a control input to reduce the error. In simple terms, the controller system monitors, adjusts, and regulates the operations of the output device to achieve a desired result. Common examples of controllers include thermostats, cruise control systems, and PID controllers.
(a) Controller PB setting when remote sensors with spans of 50°F, 150°F, and 200°F are used:
This can be calculated as;
PB = (72°F - 50°F) / (200°F - 50°F) = 0.22
(b) Controller pressure range:
The range of the controller pressure is 3 - 13 psig
(c) Controller setpoint:
The controller set point is 72°F
(d)
The controller output pressure when T = 72°F while using the same sensors as in (a) is 3 psig
(e)
The controller output pressure at T = 76°F is 6.6 psig
(f) To predict the output pressure of the controller when T = 80°F with three remote sensors having spans of 50°F, 150°F, and 200°F are used will be 11.2 psig

Consider the flow of mercury (a liquid metal) in a tube. How will the hydrodynamic and thermal entry lengths compare if the flow is laminar
Answer:
Explanation:
Considering the flow of mercury in a tube:
When it comes to laminar flow of mercury, the thermal entry length is quite smaller than the hydrodynamic entry length.
Also, the hydrodynamic and thermal entry lengths which is given as DLhRe05.0= for the case of laminar flow. It should be noted however, that Pr << 1 for liquid metals, and thus making the thermal entry length is smaller than the hydrodynamic entry length in laminar flow, like I'd stated in the previous paragraph
Why is my towns municipality being run by people from canada and a software program
It is important to note that municipalities are typically run by elected officials who are residents of the community they serve, and decisions are made based on local laws, regulations, and policies.
The use of software programs may be employed to manage certain aspects of municipal operations, such as budgeting or resource allocation, but it is unlikely that they would be used to govern the entire municipality. If you have specific concerns or questions about the leadership or management of your town's municipality, you may want to consider reaching out to your local government representatives or attending public meetings to voice your opinions and seek answers to your questions.
