A gas-turbine power plant operates on the simple Brayton cycle with air as the working fluid and delivers 32 MW of power. The minimum and maximum temperatures in the cycle are 310 compressor and 900 K, and the pressure of air at the compressor exit is 8 times the value at the inlet. Assuming an isentropic efficiency of 80 percent for the compressor and 86 percent for the turbine, determine the mass flow rate of air through the cycle. The fuel is represented by C2H6 burned with 400% theoretical air
