back to a pressure of 1 bar. Calculate the net work done, cycle efficiency and work ratio. Assume

isentropic efficiencies of turbine and compressor are 90 and 85%, respectively.

B. Air enters the compre[s1s3o4r .8of kl a /skigm, p2l7e .6g%as, t0u.r3b7in2]e plant at 100 kPa, 20°C, at a rate of2.2 kg/s. The compressor efficiency is 60%. The discharge pressure of the compressor is 450 kPa. Calculate the amount of heat (kJ/kg) that must be added to

provide a turbine inlet temperature of 650°C.
