Question 7. In the steady-flow Rankine cycle shown below, water flows at 7 kg/s.Saturated liquid water at 75 kPa exits the condenser (Stream 1). The water is pumped up to a pressure of 9 MPa (Stream 2) and is then heated in a boiler and leaves the boiler at 9 MPa and 600 °C (Stream 3). The water is expanded in a turbine and leaves the turbine at 75 kPa (Stream 4).The num The pump can be assumed reversible and adiabatic, The adiabatic turbine has an isentropic efficiency of 80%There in there is, as indicated, no pressure drop across the boiler or the condenser,Kinetic and potential energies can be neglected O Determine the specific enthalpy of stream 2,1 O Determine the actual power out of the turbine (in Determine the thermal efficiency of the cycle. marks] (d) Draw the process on a well-labelled T-s diagram. Points 1, 2, 3,and 4s and 4a should be in the right place with respect to saturation lines. The process lines should be the right shape and have the direction of water flow indicated by arrows.
