A stationary gas turbine should produce 75 MW of electricity with air into the compressor at 100 kPa, 300 K. The compression ratio is 13:1 and the highest temperature is 1600 K. With cold air properties find the cycle efficiency, exhaust temperature, and the needed flow rate of air.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
