Water vapor enters a turbine with a mass flow rate of 3 kg/s, and at a temperature and pressure of 500°C and 1 MPa, respectively. The heat loss inside the turbine is 250 kW and the steam leaves the turbine at a temperature and pressure of 150°C and 100 kPa. Neglect any changes in the velocity or the elevation. The work output of the turbine is used to operate a heat pump whose COP value is 2. Determine the rate of heat removal from the sink (1) and the rate of heat rejection to the source (2) of this heat pump. a. 3715 kW (removal), 1857.5 kW (rejection) b. 1857.5 kW (removal), 3500 kW (rejection) c. 1857.5 kW (removal), 3715 kW (rejection) d. 1500 kW (removal), 3715 kW (rejection)
