4. A steam turbine operates adiabatically with a power output of 4000 kW. Steam enters the turbine at 2100 kPa and 475 °C. The exhaust is saturated steam at 10 kPa that enters a condenser, where it is condensed and cooled to 30 °C. What is the mass flow rate of the steam, and at what rate must cooling water be supplied to the condenser, if the water enters at 15 °C and is heated to 25 °C?
