Answer:

The correct response is "821.88". A further explanation is given below.

Explanation:

According to the question,

The largest amount unresolved after five years would have been:

= \(35000\times (\frac{F}{P}, 4 \ percent,5 )\)

= \(35000\times 1.216 7\)

= \(42584.50\)

Now,

time (t) will be:

= \(5\times 12\)

= \(60 \ monthly \ payments\)

So, monthly payment will be:

= \(42582.85\times (\frac{A}{P}, 0.5 \ percent,60 )\)

= \(42584.50\times 0.0193\)

= \(821.88\)

Answer:

A) condenser pressure = 9.73 kPa,

B) 10242 kw

C) 36.9%

Explanation:

given data

entrance pressure of steam = 12.5 MPa

temperature of steam = 550⁰c

flow rate of steam = 7.7 kg/s

outer pressure = 2 MPa

reheated steam temperature = 450⁰c

isentropic efficiency of turbine( nt ) = 85% = 0.85

isentropic efficiency of pump = 90% = 0.90

From steam tables

at 12.5 MPa and 550⁰c ; h3 = 3476.5 kJ/kg,  S3 = 6.6317 kJ/kgK

also for an Isentropic expansion

S4s = S3 .

therefore when S4s = 6.6317 kJ/kg and P4 = 2 MPa

h4s = 2948.1 kJ/kg

nt = 0.85

nt (0.85) = \(\frac{h3-h4}{h3-h4s}\) = \(\frac{3476.5 - h4}{3476.5 - 2948.1}\)

making h4 subject of the equation

h4 = 3476.5 - 0.85 (3476.5 - 2948.1)

h4 = 3027.3 kj/kg

at P5 = 2 MPa and T5 = 450⁰c

h5 = 3358.2 kj/kg,  s5 = 7.2815 kj/kgk

at P6 , x6 = 0.95  and s5 = s6

using nt = 0.85 we can calculate for h6 and h6s

from the chart attached below we can see that

p6 = 9.73 kPa, h6 = 2463.3 kj/kg

B) the net power output

solution is attached below

c) thermal efficiency

thermal efficiency = 1 - \(\frac{qout}{qin}\) = 1 - ( 2273.7/ 3603.8) = 36.9% ≈ 37%

Explanation:

To determine if the rings are pure silver, we can calculate the density of the rings and compare it to the density of pure silver. The density of a material is the mass of the material per unit volume.

First, we need to find the volume of one of the rings. Since the rings are cylindrical, we can use the formula for the volume of a cylinder to find the volume of each ring:

V = π * r^2 * h

Where V is the volume of the ring, π is approximately equal to 3.14, r is the radius of the ring, and h is the height of the ring. In this case, the height of the ring is equal to the thickness of the ring, which is equal to the change in the water level (8.45 mm) divided by the number of rings (10). The radius of the ring is equal to half the diameter of the graduated cylinder (2.5 cm / 2 = 1.25 cm), since the rings are placed in the cylinder side by side.

Plugging these values into the formula, we find that the volume of each ring is:

V = 3.14 * (1.25 cm)^2 * (8.45 mm / 10) = 0.00367 cm^3

Next, we can use the mass and volume of each ring to calculate the density of the rings:

density = mass / volume

Since the mass of each ring is 0.738g and the volume of each ring is 0.00367 cm^3, the density of the rings is:

density = 0.738 g / 0.00367 cm^3 = 201.09 g/cm^3

Finally, we can compare the density of the rings to the density of pure silver, which is 10.49 g/cm^3. Since the density of the rings is much higher than the density of pure silver, it is likely that the rings are not pure silver.

It is important to note that this calculation is only an approximate estimation of the purity of the rings. There may be other factors that affect the density of the rings, such as impurities or variations in the thickness of the rings. Additionally, the value of the density of pure silver used in this calculation may not be entirely accurate, as the density of a material can vary depending on factors such as temperature and pressure. A more precise determination of the purity of the rings would require further testing and analysis.

Answer:

F = Qa*K

Explanation:

The force on the dipole is expressed as the negative gradient of the potential energy.

Thus;

Force; F = -dU/dx

Now, the potential energy is given as;

U = -pE

So, dU/dx = -pdE/dx

Since F = -dU/dx

Then, F = p*dE/dx

We are given p = Qa

Then;

F = Qa(dE/dx)

We are given that dE/dx = K

Thus;

F = Qa*K

Answer:

approximately 1.225 kg/m^3

Explanation:

Answer:

a) The y-component of velocity just before the ball hits the ground is -14.860 meters per second.

b) The ball is in the air during approximately 2.890 seconds.

c) The horizontal distance covered by the ball is 32.695 meters.

d) The magnitude of the velocity of the ball just before it hits the ground is approximately 18.676 meters per second.

e) The angle of the total velocity of the ball just before it hits the ground is approximately 52.717º below the horizontal.

Explanation:

a) The ball experiments a parabolic motion, which is a combination of horizontal motion at constant velocity and vertical motion at constant acceleration. First, we calculate the time taken by the ball to hit the ground:

\(y = y_{o} + (v_{o}\cdot \sin \theta) \cdot t+\frac{1}{2}\cdot g\cdot t^{2}\) (1)

Where:

\(y_{o}\), \(y\) - Initial and final vertical position, measured in meters.

\(v_{o}\) - Initial speed, measured in meters per second.

\(\theta\) - Launch angle, measured in sexagesimal degrees.

\(g\) - Gravitational acceleration, measured in meters per square second.

\(t\) - Time, measured in seconds.

If we know that \(y_{o} = 2\,m\), \(y = 0\,m\), \(v_{o} = 17.6\,\frac{m}{s}\), \(\theta = 50^{\circ}\) and \(g = -9.807\,\frac{m}{s^{2}}\), then the time taken by the ball is:

\(-4.904\cdot t^{2}+13.482\cdot t +2 = 0\) (2)

This second order polynomial can be solved by Quadratic Formula:

\(t_{1} \approx 2.890\,s\) and \(t_{2} \approx -0.141\,s\)

Only the first root offers a solution that is physically reasonable. That is, \(t \approx 2.890\,s\).

The vertical velocity of the ball is calculated by this expression:

\(v_{y} = v_{o}\cdot \sin \theta +g\cdot t\) (3)

Where:

\(v_{o,y}\), \(v_{y}\) - Initial and final vertical velocity, measured in meters per second.

If we know that \(v_{o} = 17.6\,\frac{m}{s}\), \(\theta = 50^{\circ}\), \(g = -9.807\,\frac{m}{s^{2}}\) and \(t \approx 2.890\,s\), then the final vertical velocity is:

\(v_{y} = -14.860\,\frac{m}{s}\)

The y-component of velocity just before the ball hits the ground is -14.860 meters per second.

b) From a) we understand that ball is in the air during approximately 2.890 seconds.

c) The horizontal distance covered by the ball (\(x\)) is determined by the following expression:

\(x = (v_{o}\cdot \cos \theta)\cdot t\) (4)

If we know that \(v_{o} = 17.6\,\frac{m}{s}\), \(\theta = 50^{\circ}\) and \(t \approx 2.890\,s\), then the distance covered by the ball is:

\(x = 32.695\,m\)

The horizontal distance covered by the ball is 32.695 meters.

d) The magnitude of the velocity of the ball just before hitting the ground (\(v\)), measured in meters per second, is determined by the following Pythagorean identity:

\(v = \sqrt{(v_{o}\cdot \cos \theta )^{2}+v_{y}^{2}}\) (5)

If we know that \(v_{o} = 17.6\,\frac{m}{s}\), \(\theta = 50^{\circ}\) and \(v_{y} = -14.860\,\frac{m}{s}\), then the magnitude of the velocity of the ball is:

\(v \approx 18.676\,\frac{m}{s}\).

The magnitude of the velocity of the ball just before it hits the ground is approximately 18.676 meters per second.

e) The angle of the total velocity of the ball just before it hits the ground is defined by the following trigonometric relationship:

\(\tan \theta = \frac{v_{y}}{v_{o}\cdot \cos \theta_{o}}\)

If we know that \(v_{o} = 17.6\,\frac{m}{s}\), \(\theta_{o} = 50^{\circ}\) and \(v_{y} = -14.860\,\frac{m}{s}\), the angle of the total velocity of the ball just before hitting the ground is:

\(\theta \approx -52.717^{\circ}\)

The angle of the total velocity of the ball just before it hits the ground is approximately 52.717º below the horizontal.

Some questions on heat transfer with answers:

1. What is heat transfer and what are the three modes of heat transfer?

Heat transfer is the process of energy transfer between objects or regions due to temperature differences. The three modes of heat transfer are conduction, convection, and radiation.

Conduction refers to the transfer of heat through direct contact between objects or particles. Convection involves the transfer of heat through the movement of fluids (liquids or gases).

Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation.

2. How does conduction occur and what factors affect the rate of conduction?

Conduction occurs when heat is transferred from a region of higher temperature to a region of lower temperature within a solid or between solids in contact. The rate of conduction is influenced by factors such as the thermal conductivity of the material, the temperature difference across the material, the cross-sectional area of the material, and the distance over which heat is transferred.

3. What is the difference between natural convection and forced convection?

Natural convection is the mode of heat transfer that occurs due to density differences caused by temperature variations. It involves the transfer of heat through the movement of fluids caused by buoyancy effects, such as hot air rising and cold air sinking.

Forced convection, on the other hand, is the mode of heat transfer that occurs when an external force, such as a fan or pump, is used to actively circulate the fluid and enhance the heat transfer rate.

4. How does radiation heat transfer work and what factors affect the rate of radiation?

Radiation heat transfer occurs through electromagnetic waves without the need for a medium. It can occur between objects at different temperatures, even in a vacuum.

The rate of radiation heat transfer is influenced by factors such as the emissivity of the objects (a measure of their ability to emit radiation), their temperature, the surface area and geometry of the objects, and the presence of intervening materials that may absorb or reflect the radiation.

5. How is heat transfer important in everyday life and engineering applications?

Heat transfer plays a crucial role in various aspects of everyday life and engineering applications. It is involved in processes like cooking, heating and cooling systems, power generation, refrigeration, and many industrial processes.

Understanding heat transfer allows engineers to design efficient heat exchangers, thermal insulation systems, and cooling mechanisms. It is also essential in fields such as material science, aerospace engineering, electronics cooling, and environmental studies, enabling the efficient transfer and control of thermal energy for practical applications.

The maximum value of effective stress in the past divided by the present value, is defined as the over-consolidation ratio.

The maximum effective stress in the past divided by the present value of effective stress is defined as the over-consolidation ratio. Consolidation is the process of soil settling over time when subjected to a static load. Soil is over-consolidated when it has undergone consolidation in the past and has a maximum effective stress that is higher than the current effective stress.The over-consolidation ratio (OCR) is a measure of the degree of over-consolidation of the soil. It is calculated by dividing the maximum past effective stress by the current effective stress. The OCR is a critical parameter in soil mechanics, as it is used to estimate the amount of settlement that can occur in a soil deposit. The greater the OCR, the less likely the soil is to settle further, and the more stable it is.

Voltage : Vin = Vin(t) = sin(ωt)

Resistance R = 100Ω

According to Ohm's law, Voltage in a circuit is directly proportional to current flowing through it.

The proportionality constant in this case is equal to resistance.

So,

V ~ R

V = IR

as it is given that,

V = sin(ωt)

The maximum value of sign function is equal to 1.

So the maximum voltage in given case = V = 1 volt

Resistance given R = 100Ω

So,

Current according to Ohm's law : I = V/R

Gauge Pressure = 408.3 KPa

Explanation:

The pressure inside the pipe can be given in terms of the elevation, by the following formula:

P = ρgΔz

where,

P = Absolute Pressure = ?

ρ = Density of Water = 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

Δz = elevation = 52 m

Therefore,

P = (1000 kg/m³)(9.8 m/s²)(52 m)

P = 509.6 KPa

Now, for gauge pressure:

Gauge Pressure = P - Atmospheric Pressure

Gauge Pressure = 509.6 KPa - 101.3 KPa

Gauge Pressure = 408.3 KPa
