1. 1 kg of air is polytropically compressed reversibly from 5 bar to 10 bar from an initial temperature of 300°C. Find the transferred heat and the change in entropy. Take the polytropic index as 1.25.
2. 0.5 kg of dry air is expanded reversibly to a final temperature of 100 °C. The work done by the system is 1000kJ. Determine the change in entropy of the system. Take the polytropic index as 1.2.
3. Determine the change in entropy for 1.0 mole of an ideal gas originally confined to one-half of a 5.0-L container when the gas is allowed to expand to fill the entire container at constant temperature.
What is the work you get out of each kJ of heat extracted from the basin? Repeat for the case that the water is at 100C. Comment on why efficient car engines run so hot.
A solid circular shaft made of 304 stainless steel uniformly tapers from a diameter of 1.5 inches to a diameter of 1.0 inches over a length of 3 feet. Objective: If the shaft transmits 100 hp at 2000 RPM, determine the maximum shear stress in the sha..
a wind tunnel has a 1-m2 6-m-long test section in which air at standard sea-level conditions moves at 70 ms. it is
refrigerant-134a enters the evaporator coils placed at the back of the freezer section of a household refrigerator at
in space a novel heat rejection scheme that has been proposed for heat dissipation is termed a liquid droplet radiator
A current carrying 10 gauge (.1013-in dia) copper wire is insulated with a .05 in thick layer of rubber. The maximum temperature of thr rubber is 200F when the temperature of the air is 120F. The external heat transfer coefficient can be taken as 4 B..
A certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 60 m diameter blades at that location. Take the air density to be 1.25 kg/m³.
what are the three principal types of critical system ? explain the differences between these.
