Air is compressed from 23 C to 100 kPa to 500 kPa in a gas turbine. The air is heated to 520 C in the regenerator and then to 1200 C before entering the turbine. The isentropic efficiency is 100% for both the compressor and turbine. Please draw and label the T-s diagram, determine the regenerator effectiveness, the cycle thermal efficiency and the back work ratio.
A balanced-cross-flow compact heat exchanger is required for an air heating system that processes 0.5 kg/s air. The inlet temperature for the hot water is 295 K, and the cold air enters at 270 K to be heated to 287 K. The inlet pressure for the hot w..
Carbon dioxide gas enters a pipe at 3 MPa and 500 K at a rate of 2 kg/s. CO2 is cooled at constant pressure as it flows in the pipe and the temperature of CO2 drops to 450 K at the exit. Determine the volumetric flow rate and the density of carbon di..
A piston contains 0.5kg of water. The initial volume of the piston is 0.125 m3 and the pressure inside the piston is 300kPa. The water is expanded to a volume of .31701 m3. The pressure inside the piston remains constant. Determine the amount of heat..
