Explanation:

The closest equivalent present worth of John's deposits is less than $8,000.

To determine the closest equivalent present worth of John's deposits, we need to calculate the present value of the cash flows he will make.

The deposit of $1000 at the end of the next year can be considered a future value (FV). We need to calculate its present value (PV) using the formula:

PV = FV / (1 + r)^n

Where:

FV = $1000

r = interest rate = 10% = 0.10

n = number of years = 1

PV = $1000 / (1 + 0.10)^1 = $909.09

Next, we calculate the present value of the increasing deposits of $100 per year for 10 years. These cash flows form an arithmetic progression with a common difference of $100.

Using the formula for the sum of an arithmetic progression, we can find the present value of these cash flows:

PV = (n/2) * (2a + (n-1)d)

Where:

n = number of terms = 10

a = first term = $100

d = common difference = $100

PV = (10/2) * (2*100 + (10-1)*100) = 5 * (200 + 9 * 100) = $5,500

Now, we can sum up the present values of both cash flows:

PV = $909.09 + $5,500 = $6,409.09

The closest equivalent present worth is between $8,000 - $8,300. Since the calculated present value is lower than $8,000, the closest equivalent present worth is less than $8,000.

Answer:

a) The maximum flowrate of the pump is approximately 13,305.22 cm³/s

b) The pressure difference across the pump is approximately 293.118 kPa

Explanation:

The efficiency of the pump = 78%

The power of the pump = 5 -kW

The height of the pool above the underground water, h = 30 m

The diameter of the pipe on the intake side = 7 cm

The diameter of the pipe on the discharge side = 5 cm

a) The maximum flowrate of the pump is given as follows;

\(P = \dfrac{Q \cdot \rho \cdot g\cdot h}{\eta_t}\)

Where;

P = The power of the pump

Q = The flowrate of the pump

ρ = The density of the fluid = 997 kg/m³

h = The head of the pump = 30 m

g = The acceleration due to gravity ≈ 9.8 m/s²

\(\eta_t\) = The efficiency of the pump = 78%

\(\therefore Q_{max} = \dfrac{P \cdot \eta_t}{\rho \cdot g\cdot h}\)

\(Q_{max}\) = 5,000 × 0.78/(997 × 9.8 × 30) ≈ 0.0133 m³/s

The maximum flowrate of the pump \(Q_{max}\) ≈ 0.013305 m³/s = 13,305.22 cm³/s

b) The pressure difference across the pump, ΔP = ρ·g·h

∴ ΔP = 997 kg/m³ × 9.8 m/s² × 30 m = 293.118 kPa

The pressure difference across the pump, ΔP ≈ 293.118 kPa

Answer:

This is not an engineering question.

Explanation:

a)  The initial and final temprature are 99.61°C and T3 = 259.07°C

b)   The mass of liquid water when the piston first start moving is 0g

Using the data provided:

Initial Pressure = P1 = 125kPa

Mass of Saturated Vapor Liquid = m = 5kg

Initial Mass of Liquid water = mf = 2kg

Initial Mass of Vapor = mg = 3kg

The temperature for a mixture of liquid steam saturated with water according to the thermodynamic table is:

T₁ = 99.61°C

The specific volume is:

vf = 0.001043m³/kg

And the saturated volume is:

vg = 1.6941m³/kg

Therefore, the volume in state 1 will be equal to:

V1 = mfvf + mgvg

V1 = (2kg)(0.001043m³/kg) + (3kg)(1.6941m³/kg)

V1 = 5.084m³

In state 3 then the volume will be equal to:

V3 = 1.2V1

V3 = 1.2(5.084m³)

V3 = 6.1008m³

Then the specific volume will be equal to:

v3 = V₃/m

v3 = 6.1008m³/5kg

v3 = 1.2202m³/kg

For a pressure of 300 kPa and the previous specific volume found through the thermodynamic table, the value of the temperature is:

T3 = 259.07°C

Question b) When the piston first stats moving at P₂ = 300kPa and V₂ = V₁ = 5.084m³

v₂ =V₂/m

v₂ = 5.084m³/5kg

v2 = 1.0168m³/kg

While at 300 kPa the value of the vapor saturated vg = 0.88578m³/kg This implies that the condition is met:

v2 > vg

Therefore, no liquid is there in-cylinder when piston stats moving, mf = 0kg

The average shear stress, Tavg, is equal to 0.06 pu2., Solving for the drag coefficient of the bar, CD, yields: 2.40.

What is shear stress?
An object experiences deformation whenever an external force acts upon it. if the force's direction is parallel to the object's plane. Along that plane, there will be a deformation. The object in this instance is under shear or tangential stress. It happens so when force vector components that are perpendicular to the material's cross-sectional area. The force vectors for normal/longitudinal stress will be parallel to the cross-sectional area that it affects.

(a) The average shear stress, Tavg, is equal to the dynamic pressure pu2 divided by the width of the bar, h. Therefore,
Tavg = pu2/h
Rearranging for the dynamic pressure pu2 yields:
pu2 = Tavg h
Substituting the given value of Tavg as 0.06 pu2 gives:
pu2 = 0.06 pu2 x h
Solving for h yields:
h = pu2/0.06 pu2
Therefore, the average shear stress, Tavg, is equal to 0.06 pu2.

(b) The drag coefficient of the bar, CD, is equal to the drag force (Fd) divided by the dynamic pressure (pu2) times the area (A) of the bar. Therefore,
CD = Fd/(pu2 x A)
Rearranging for Fd yields:
Fd = CD x pu2 x A
Substituting the given values for CD, pu2, and A gives:
Fd = 2.40 x pu2 x (h x L)
Solving for the drag coefficient of the bar, CD, yields:
CD = Fd/(pu2 x A) = 2.40

Solar heat gain coefficient (SHGC) measures how well a window allows heat from the sunlight to pass through it.

The solar heat gain coefficient (SHGC) is a value that represents the amount of solar radiation, in the form of heat, that can pass through a window or glazing system. It measures the ability of the window to transmit solar energy from the sunlight into the interior space. A higher SHGC indicates that the window allows more solar heat to pass through, which can contribute to increased solar heat gain and potentially higher cooling loads. On the other hand, a lower SHGC indicates that the window has better heat-blocking properties, reducing the amount of solar heat entering the building and potentially lowering cooling needs. The SHGC is an important factor to consider when selecting windows for energy efficiency and managing indoor thermal comfort.

Basically, the Constitution accords powers to the national or federal government and these includes; enumerated or delegated, reflected, and concurrent powers. Therefore, base on the US Constitution, any law, act, or license issued and approved by the federal government supercedes or overrides any state law.

In this scenario, NatGas Corporation obtains a federal license to operate a gas pipeline through a certain area of Oregon. The Oregon state legislature enacts a law that bans gas pipelines in that area. Most likely, the state law violates the U.S. Constitution because a federal law is supreme.

The rest is straightforward...

To calculate the theoretical power required to operate the compressor in a 10-ton-capacity refrigeration system using ammonia (r-717) under saturated conditions, we can use the following formula:Power = mass flow rate x specific enthalpy changeFirst, we need to determine the mass flow rate of the refrigerant. We can do this using the following formula:

Mass flow rate = refrigeration capacity / (specific enthalpy change x refrigerant density)
Since the refrigeration capacity is given as 10 tons, we need to convert this to kilowatts (kW) by multiplying by 3.517:
Refrigeration capacity = 10 tons x 3.517 kW/ton = 35.17 kW
Next, we need to determine the specific enthalpy change of the refrigerant. This can be found by subtracting the specific enthalpy of the refrigerant in the evaporator from the specific enthalpy of the refrigerant in the cSpecific enthalpy change = h2 - h1
To find the specific enthalpies, we can use a refrigerant table. For ammonia (r-717) at 210 kPa, the specific enthalpy in the evaporator (h1) is 349.7 kJ/kg, and at 750 kPa, the specific enthalpy in the condenser (h2) is 400.8 kJ/kg.Substituting these values into the formula, we get:Specific enthalpy change = 400.8 - 349.7 = 51.1 kJ/kg
Finally, we need to determine the refrigerant density. At 210 kPa, the density of ammonia (r-717) under saturated conditions is 480 kg/m³.Substituting all of these values into the mass flow rate formula, we get:
Mass flow rate = 35.17 kW / (51.1 kJ/kg x 480 kg/m³) = 1.007 kg/s
Now we can use the power formula to calculate the theoretical power required to operate the compressor:Power = 1.007 kg/s x 51.1 kJ/kg = 51.48 kWTherefore, the theoretical power required to operate the compressor in a 10-ton-capacity refrigeration system using ammonia (r-717) under saturated conditions is approximately 51.48 kW.

The right answer is B. The reaction will never be possible since the Gibbs energy will always be positive.

Gibbs free energy, G, enthalpy, H, and entropy, S are related as follows:

ΔG = ΔH - TΔS

We will always have a positive value for the Gibbs free energy if enthalpy is positive and entropy is negative.

This means that choice B is the best one. A reaction will always be possible if it is exothermic (H is negative), has a positive entropy change (S is positive), and G is always negative. The sign of G determines whether a response (or other physical change) is possible. The reaction cannot take place if G is positive.

The complete question is- What can you determine about the feasibility of a reaction if the enthalpy is positive and the entropy is positive?

A. The Gibbs energy will always be positive, and the reaction will never be feasible.

B. The Gibbs energy will always be negative, and the reaction will always be feasible.

Explanation:

Answer:

A.) Time = 17.13 seconds

B.) Distance = 31.9 m

C.) V = 11.18 m/s

D.) V = 7.1 m/s

Explanation:

The initial velocity U of the automobile is 15.65 m/s.

 At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile with initial velocity U = 0 at a constant acceleration of 1.96 m/s². Because the police is starting from rest.

For the automobile, let us use first equation of motion

V = U - at.

Acceleration a is negative since it is decelerating with a = 3.05 m/s² . And

V = 0.

Substitute U and a into the formula

0 = 15.65 - 3.05t

15.65 = 3.05t

t = 15.65/3.05

t = 5.13 seconds

But the motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s².

The total time required for the police car to overtake the automobile will be

12 + 5.13 = 17.13 seconds.

b.) Using the third equation of motion formula for the police car at V = 11.18 m/s and a = 1.96 m/s²

V^2 = U^2 + 2aS

Where S = distance travelled.

Substitute V and a into the formula

11.18^2 = 0 + 2 × 1.96 ×S

124.99 = 3.92S

S = 124.99/3.92

S = 31.88 m

c.) The speed of the police car at the time it overtakes the automobile will be in line with the speed zone which is 11.18 m/s

d.) That will be the final velocity V of the automobile car.

We will use third equation of motion to solve that.

V^2 = U^2 + 2as

V^2 = 15.65^2 - 2 × 3.05 × 31.88

V^2 = 244.9225 - 194.468

To calculate the flow rate of the oil through the 2-inch schedule 40 pipe using an orifice meter and a water manometer, we need to apply the principles of fluid mechanics and orifice meter equations.

Pipe diameter (D) = 2 inches

Pipe schedule (sch) = 40

Oil temperature (T) = 50°F

Specific gravity of oil (SG) = 0.85

Viscosity of oil (μ) = 15 cP

Orifice diameter (d) = 1.5 inches

First, we need to convert the units of diameter and temperature to a consistent system. Let's use SI units (meters and Kelvin) for calculations.

1 inch = 0.0254 meters

2 inches = 2 * 0.0254 meters = 0.0508 meters

1.5 inches = 1.5 * 0.0254 meters = 0.0381 meters

50°F = (50 - 32) × 5/9 = 10°C = 283.15 K

Now, we can calculate the flow rate using the orifice meter equation:

Q = Cd * A * sqrt(2 * ΔP / ρ)

Where:

Q = Flow rate

Cd = Discharge coefficient (depends on the orifice plate design, typically around 0.6-0.8)

A = Cross-sectional area of the orifice (π * (d/2)^2)

ΔP = Pressure drop across the orifice

ρ = Density of the fluid

First, let's calculate the density of the oil:

ρ = SG * ρwater (ρwater = 1000 kg/m^3)

ρ = 0.85 * 1000 kg/m^3 = 850 kg/m^3

Next, let's calculate the cross-sectional area of the orifice:

A = π * (d/2)^2 = π * (0.0381/2)^2

A = 0.0011375 m^2

We need the pressure drop across the orifice to calculate the flow rate. The pressure drop can be measured by the water manometer. However, the details about the specific water manometer setup are not provided in the question. We need the height difference or pressure difference measured by the water manometer to proceed further. Please provide the necessary information regarding the water manometer setup or the pressure difference so that we can calculate the flow rate accurately.

A pool of contaminated water is lined with a 40 cm thick containment barrier. The contaminant in the pit has a concentration of 1.5 mol/L, while the groundwater circulating around the pit flows fast enough that the contaminate concentration remains 0. There is initially no contaminant in the barrier material at the time of installation. The governing second order, partial differential equation for diffusion of the contaminant through the barrier is:

dC/dt = D( d²C / dz²)

where c(z,t) represent the concentration of containment of any depth into the barrier at anytime and D is the diffusion coefficient (a constant) for the containment in the barrier material.

a) write all boundary and initial conditions needed to solve this equation for C(z, t)

b) Find the steady  state solution (infinite time) for C(z)

Answer:

a) At t = 0, z= 0, c = 1.5 mol/L

at t =0, z = 0.4m, c = 0 mol/L

b) C(z) = z² - 4.15z + 1.5

Explanation:

a)

The boundary and initial conditions are as follows

At t = 0, z= 0, c = 1.5 mol/L

at t =0, z = 0.4m, c = 0 mol/L

b)

The governing second order, partial differential equation for diffusion of the contaminant through the barrier is :

(dC/dt) = D*(d²C/dz²) ..............equ(1)

For steady state, above equation becomes,

(d²C/dz²) =0

Integrating above equation,

(dC/dz) = Z + C1  { where C1 is integration constant) }

again integrating above equation,

C = z² + C1*z + C2    ...................equ(2)

applying boundary condition : at t =0, z= 0, c = 1.5 mol/L, to above equation

 C = z² + C1*z + C2

1.5 = 0 + 0*0 + c2

C2 = 1.5

applying boundary condition : at t =0, z= 0.4m, c = 0 mol/L, to equation (2) ,

0 = 0.4² + C1*0.4 +  1.5

0 = 0.16 + 0.4C1 + 1.5

0.4C1 = - 1.66

C1 = -1.66/0.4

C1 = -4.15

So, the steady state solution for C(z) is:

C(z) = z² - 4.15z + 1.5
