An open system Brayton cycle is used in a power plant. The atmospheric inlet conditions of the compressor are: temperature 30C and pressure 100kPa and the pressure at its outlet is 1200kPa. The volumetric flow rate at the inlet of the compressor is 150m^3/min. At the exit of the turbine the temperature is 500°C. The Compressor and turbine have isentropic efficiencies of 82 and 88 percent respectively and the heat in is 2065 kW. Using variable specific heats
Determine:
a) The net power output
b) The thermal efficiency
c) The back work rate
d) Show with procedure and explain how you would solve problem 2 if the Qin was not given.
