Problem 2.

Problem 1.

An ideal Rankine Cycle with reheat uses water as the working fluid with a flow rate of 0.15 kg/s.
At the inlet of the turbine (state 1) the water is a superheated vapor at 475ºC and 11 MPa.
The pressure at the exit of the first stage of the turbine is 0.9 MPa.
The reheat temperature (state 3) is also  475ºC.  
The condenser pressure is 8 kPa, and the water exits as a saturated liquid

Find: (a) The heat addition to the cycle, (b) the consumption rate of U-235 to maintain the heat addition if this is a nuclear power plant, and (c) the consumption rate of natural gas to maintain the cycle

Problem 2.

Re-do problem 1 using an isentropic efficiency of 80% for both stages of the turbine and the pump
