The inlet temperature of an air compressor is T₁=300°K and the outlet temperature is T2-500°K. The compressor operates at a mass flow rate of 0.093kg/sec and the heat lost during the compression is 10kJ/kg. Assume that the air is an ideal gas with Cp=1.004 kJ/(kg°K). Calculate the mechanical power needed to be provided to the compressor shaft. Present your answer in kilo- Watts (kJ/sec).
Box the final answer. Write legibly. Steam flows into a turbine at a rate of 3.5 kg/s and ¾ MW of heat are lost from the turbine. Ignoring elevation and kinetic energy effects, calculate the power output from the turbine in KW? Steam pressure entering the turbine is 62 Bar at 440ºC and leaves at 74 Kpa.

An ideal gas passes a diffuser. At the diffuser inlet, the temperature is T1 = 350.00 K, the pressure P1 = 100.00 kPa, the velocity V1 = 200.00 m/s, and the inlet area A1 = 0.30 m2. At the exit, the velocity is very small. The specific heat of the ideal gas at the constant pressure is cp = 1.0050 kJ/(kg·K). The gas constant is R = 0.2870 kPa·m3/(kg·K).
