1. For an ideal, regenerative Rankine cycle utilizing steam as the working fluid, water enters the boiler (State 1) at 2000 psi, becomes heated, and enters the turbine (State 2) at 2000 psi and 1080 deg F. Some of the steam is extracted from the turbine (State 3) at 160 psi and is directed to an open feedwater heater to heat the feedwater. The remaining steam exits the turbine (State 4) at 1.0 psi and enters the condenser. The condensed liquid is pumped into the open feedwater heater by Pump #1, and then is pumped from the open feedwater heater to the boiler by Pump #2. a) Draw the schematic arrangement and T-S diagram indicating all states. NOTE: base it on the diagram shown in class (and in Content in BB) but note that the state numbering system is different. Number the diagrams according to this problem. b) Determine work for both pumps. c) Determine steam extraction percentage going to the open feedwater heater. d) Determine turbine work, net work, and cycle efficiency. 1.
