I have been given two questions to solve, the first of the two I solved which is: 'Consider an idea gas turbine cycle with stages of compression and two stages of expansion. Thepressure ratio across each stage of the compressor and turbine is 3. The air enters each stage of thecompressor at 300 K and each stage of the turbine at 1200 K. The cycle has a net power output of110kW. Find the mass flow rate of the air that passes through the engine.' I solved this as follows:1. pressure ratio at state 1 = 1.3862. pressure ratio at state 2 = 4.1583. the enthalpy at state 2 = 411.27 KJ/kg and state 4 = 1277.79 KJ/kg4. pressure ratio at state 5 = 2385. pressure ratio at state 6 = 79.336. work input into the compressor = 221.14 KJ/kg7. work output of the turbine = 662.86 KJ/kg8. net work done by the gas turbine = 440.72 KJ/kg9. mass flow rate = 0.25 kg/s The part I need help in is the follow up question to the one i solved above which is as follows: 'Reconsider the previous problem but now…
