A newly purchased sedan car operates on an ideal thermodynamic cycle. The engine has acompression ratio of 10. The ambient air pressure is 1 bar while temperature is 21 ºC. Themaximum temperature in the engine is 1600 K. Draw the ideal power cycle and label it.Utilizing the air-standard assumptions, determine (a) the gas temperature at the exits of thecompression and the expansion processes, (b) the specific works of compression, expansionand net, (c) heat supplied to the engine and (d) the thermal efficiency.

A turbojet is flying with a velocity of 900 ft/s at an altitude of 20,000 ft, where the ambient conditions are 7 psia and 10°F. The pressure ratio across the compressor is 13, and the temperature at the turbine inlet is 2400 R. Assuming ideal operation for all components and constant specific heats for air at room temperature, determine the velocity of the exhaust gases.
