Repeat Problem 7.46 assuming the steam turbine and the air compressor each has an isentropic efficiency of 80%.

Problem 7.46

A certain industrial process requires a steady supply of saturated vapor steam at 200 kPa at a rate of 0.5 kg/s. Also required is a steady supply of compressed air at 500 kPa at a rate of 0.1 kg/s. Both are to be supplied by the process shown in Fig. P7.46. Steam is expanded in a turbine to supply the power needed to drive the air compressor, and the exhaust steam exits the turbine at the desired state. Air into the compressor is at the ambient condition, 100 kPa, 20?C. Give the required steam inlet pressure and temperature, assuming that both the turbine and the compressor are reversible and adiabatic.
