Question

2. (50 pts.) Consider a steady-state, steady-flow, regenerative power cycle with one closed feedwater heater. The mass flow rate of water going through the steam generator is 8 kg/s. The figure and table below provide some of the data needed for solving this problem, eg. you do not need to look up enthalpies in the tables. Calculate (a) The extracted flow fraction a (b) The total turbine power (kW) (c) The total pump power (kW) (d) The boiler heat transfer (kW) (e) The thermal efficiency for this cycle The maximum thermal fficiency that this cycle could theoretically have and arrows showing flow directions (8) Bonus (5 pts: No Partial Credit): Complete the T-s diagram with all states points, p pressures, temperatures, Note: Show ALL your work, step by step!
