3. Steam at 30 bar and 500C enters a pass-out turbine at a rate of 18000 kg h -1 . The bulk of this steam is expanded isentropically to a condenser pressure of 0.03 bar, but 32% is bled from the turbine at a pressure of 3 bar for process heating. If the condensate from the process heater is directly pumped back to the boiler, find:

(a) the power output from the turbine

(b) the rate of process heating

(c) the efficiency of the plant
