What is the amount of shaft work produced by a typical IC engine per gallon? The remainder of the energy released in the combustion is in the form of heat.
How much energy (in ft-lbf, Btu, and kJ) is required to accelerate my 3400 pound car from rest to a velocity of 60 mph on a level stretch of road?
The process also requires that the temperature not change during the stirring, so energy is removed from the liquid by heat transfer. How much heat transfer is required?
Refrigerant-134a at 240 kPa and 20 degree Celsius undergoes an isothermal process in a closed system until its quality is 20 percent.
What is the temperature at the outer surface of the cellular glass insulation? Draw schematically the isotherms inside the soil and the heat flux plot.
The box's surface is the 12"x36" side, and the 2"x2" surface is directly in the center of the prism. What is the stress caused on the prism by being placed on this pedestal, what are the moments if
The velocity of the water coming out is 0.75 m/s. Calculate how many hours he should urn the pump to get the full 100,000L he is allowed.
If the house size is approximately 30 by 10m and the wall height is 2.6m what is the maximum temperature the inside of the house will heat up to once steady state is reached?
Estimate the time intervals and uncertainties in measured mass flow rate that would result from using 100, 500, and 1000 mL beakers.
Draw the system diagram for the Rankine cycle. Label all of the states. Draw the T-v diagram for the cycle. Label your states so they also agree with your system diagram.
If the surroundings are at 15 psia and 75 F, determine the entropy generated by this process , the exergy destroyed, and the second law efficiency. Will this process actually occur?
Determine the heat generation rate of the portable heater. What are the temperatures at the inner and outer surfaces of the laboratory chamber?
You graduated from college after 4 long years and studying finally paid off! Draw the cash flow diagram and show your work.
Determine the heat loss rate of this mixing chamber. If all the heat loss to the surrounding at 25 degree Celsius, determine the rate of total entropy generation during this mixing process.
Write the stream function and velocity potential as a function of the three source/sink strengths. Write the expressions for the velocity components in terms of the three source/sink strengths.
Compute, if possible, both the velocity potential and the stream function. Identify any stagnation points in this potential flow field. If it isn't a flow tell how you would identify them if it was.
If a stream function and a velocity potential exist, sketch both the streamlines the equipotential lines and the pressure field using the pressure at the origin to normalize.
The exhaust mass flow rate is constant at 21 lb m/s. Determine the value of the restraining force Fx. Assume the exhaust flow is essentially horizontal.
Suppose another stone is thrown horizontally from the same building. If it strikes the ground 67 m away.
Suppose a ski-jumper lands at a point 157 m down the incline of the track described in the example (with a horizontal take-off). What was her speed at take-off?
Determine an equation for the time at which the projectile strikes the building. (Use any variable or symbol stated above as necessary.)
A particle initially located at the origin has an acceleration of = 2.6 m/s2 and an initial velocity of i = 5.3 m/s. Find the velocity of the particle at t = 6.0 s.
A projectile is launched straight upward at +73.5 m/s from a height of 93.0 m, at the edge of a sheer cliff. Find the maximum height of the projectile above the point of launch.
