Consider a regenerative gas-turbine power plant with two stages of compression and two stages of expansion. The overall pressure ratio of the cycle is 9. Argon enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Assuming constant specific heats, determine the minimum mass flow rate of argon needed to develop a net power output of 120.0 MW. The properties of argon at room temperature are $c_p$ = 0.5203 kJ/kg. K and k = 1.667. The minimum mass flow rate of argon is kg/s.
