Problem 2.

Problem 1.

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

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

Problem 2.

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