Steam is expanded in an adiabatic turbine from 3 MPa and 400 C to 30 kPa. The turbine generates 4947kW of power when the steam mass flow rate is 21,600 kg/hr. What is the isentropic efficiency of the turbine? What is the actual exit temperature (and quality if applicable)? Air is compressed from atmospheric pressure at 20 C to 700 kPa in an adiabatic compressor (steady flow device) at a flow rate of 3 kg/s. The compressor has an isentro pi c efficiency of 95%. Assume constant specific heats for air.
What is the power required to compress the air?
What is the ACTUAL outlet temperature of the air?
