a) An adiabatic turbine expands steam from 500?C and 3.5 MPa to 200?C

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 exiting steam is at 150?C and 0.3 MPa, what will be the power developed by the turbine if the inlet steam conditions and flow rate are unchanged?
