I need full steps answer please.
A piston-cylinder device contains nitrogen gas at 150 kPa, 20 degree C, at 0.5 m3. The gas is compressed to 400 kPa and 140 degree C while 11 kJ of heat is removed from the cylinder. Determine the work (kJ) required to compress the nitrogen. Refrigerant R134a at 800 kPa and 25 degreeC is throttled to a pressure of 120 kPa. (a) Determine the final temperature (degree C). Draw (b) P-v, (c) T-v, and (d) T-s diagrams for this process. Air enters a compressor at 100 kPa, 50 degree C, at a rate of 60 kg/hr. The compressor requires 1.1 kW of work. The air exits the compressor at 130 kPa and enters in an aftercooler heat exchanger to reduce the temperature of the air. If the air exits the aftercooler at 70 degree C, determine the mass flow rate (kg/s) of the cooling water through the aftercooler.Explanation / Answer
