4) (11 pts each) Consider an ideal Rankine cycle with a mass flow rate of (0.3+ 0.002 y) kg/s (That is, if y = 12 then the heat addition is

0.324 kg/s. The condenser is at 5 kPa and the entrance to the turbine is at 800°C and 7.0MPa. Find the following: a. The rate of work of the pump: b. The rate of heat addition in the boiler: boilerc. The rate of work of the turbine:W surb =
