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 if the Qin was not given.
You do not need to get numbers for this problem.
