value of y is ____4___

Consider an ideal Rankine Cycle using H2O as the fluid medium. The condenser is at y kPa. (That is, if y = 3 the condenser pressure is 3 kPa). The water exits the boiler at 9 MPa and 600oC. The mass flow rate of the water is (0.25 + y/200) kg/s. (That is, if y =3, then the mass flow is 0.265 kg/s).

  1. Find the temperature at the pump exit.                                                 T2 = __________ oC (+ 0.1 oC)
  2. Find the rate of work of the pump.                                                           Wpump = __________ W (+ 20 W)
  3. Find the temperature at the exit of the turbine.                                  T4 = _____________ oC (+ 0.1 oC)
  4. Find the net rate work for the cycle. Wnet = _________ kW (+ 1 kW)
  5. Find the cycle thermal efficiency.                                                              h = ___________ (+ 0.5 %)
