Question 4:
Steam enters the turbine of a Rankine cycle at 16 MPa, 560 °C. The condenser pressure is 8 kPa.
The turbine and pump each have isentropic efficiencies of 100%, and the mass flow rate of steam
entering the turbine is 120 kg/s. Determine
(a) The net power developed, in kW
(b) The rate of heat transfer to the steam passing through the boiler, in kW
(c) The thermal efficiency
[Hint]
Note 1: thermal efficiency of the cycle: $\eta = \frac{W_{cycle}}{Q_{in}}$
Note 2: if the subscript $p, i$ denotes the pump inlet state and $p,o,s$ denotes pump outlet isentropic
state, then: $h_{p,o,s} = h_{p,i} + v_{p,i} (p_{p,o,s} - p_{p,i})$
