Question

Air under pressure of 100 kPa at 280 K enters the compressor and is stably compressed to 600 kPa and a temperature of 400 K. The mass flow rate of the air is 0.02 kg/s and heat loss is 16 kJ/kg during the process. Ignoring changes in kinetic and potential energy, determine the input power of the compressor.

Answers (~1.9kJ, ~1.1kJ, ~4kJ) The figure to the right shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft with a cross- sectional area of 1.0 cm² is attached to the top of the piston. The total mass of the piston and shaft is 35 kg. While the gas is slowly heated, the internal energy of the gas increases by 0.25 kJ, the potential energy of the piston-shaft combination increases by 0.5 kJ, and a force of 1300 N is exerted on the shaft as shown in the figure. The piston and cylinder are both good insulators and friction between them is negligible. The local atmospheric pressure is 1 bar and g = 9.81 m/s².
