CHEG 2313 Thermo I HW#9 Spring 2011 Due Wednesday, April 13, 2011 in class. 1. A power plant using an ideal Rankine power generation cycle operates a boiler at a pressure of 500 bar with an outlet temperature of 800 ° C. The condenser produces saturated liquid water at 25 bar. Determine the following: a) The work produced by the turbine per kg. (3 pts) b) The heat given off by the condenser per kg. (2 pts) c) The work required by the pump per kg. (2 pts) d) The heat used by the boiler. (2 pts) e) The overall efficiency of this Rankine cycle. (2 pts) 4 1 2 3
