a. An adiabatic turbine expands steam from 500 degree celsius and 3.5 MPa to 200 degree celsius and 0.3 MPa. If the turbine generates 750 kW, what is the flow rate of steam through the turbine?
b. If a breakdown of the thermal insulation around the turbine allows a heat loss of 60 kJ per kg of steam, and the existing steam is at 150 degree celsius and 0.3 MPa, what will be the power developed by the turbine if the inlet steam conditions and flow rate are unchanged?
