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 16 . The argon enters each stage of the compressor at \( 300 \mathrm{~K} \) and each stage of the turbine at 1300 K. Accounting for the variation of specific heats with temperature, Determine the minimum mass flow rate of air needed to develop a net power output of 120 MW. (kargon= 1.667)
