2019 Exam - Thermodynamics Mech3001 - Question 4

Exam from 2019 MECH301 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. The working fluid Argon enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Determine the minimum mass flow rate of argon needed to develop a net power output of 110 MW. Treat Argon as an ideal gas with constant specific heats.
