7. A steam turbine (efficiency 72%) drives an air compressor (efficiency 80%). Assuming air can be treated as an ideal gas with constant specific heat, what mass flow rate of air, in kilograms per hour, can be compressed? PIN = 2 MPa IN TIN = 350C mST = 0.1 kg/s m=0.72 Turbine Compressor = 0.80 = 1 atm POUT = 8 kPa IN TIN = 27C POUT = 5 atm
