Consider a steam power plant operating on a simple ideal
Rankine cycle and having a net power output of 57 MW. The steam
enters the turbine at 9 MPa and 575 ° C and exits at 150 ° C, then
it is cooled in the condenser to a pressure of 100 kPa by means of
the cooling water from a lake and that circulates through the
condenser tubes to a rate of 1370 kg / s. Consider leaving the pump
at 120 ° C. Show the cycle on a Ts diagram with respect to the
saturation lines, as well as the real and isentropic working lines
of the turbine and the pump, determine a) the cycle efficiency, b)
the isentropic efficiency of the turbine, c) the isentropic
efficiency of the pump and d) the mass flow of the steam.

The net power of a steam power plant operating according to the
simple ideal Rankine cycle is 30.5 MW. Water vapor enters the
turbine at 7 MPa pressure and 500 ° C, expands to 10 kPa condenser
pressure in the turbine. The steam is condensed in the condenser by
cooling it with water from a lake. The flow rate of the lake water
is 1950 kg / h. Get the pump and turbine adiabatic efficiency of
87%. Show the cycle...

Consider a steam power plant operating on a simple ideal Rankine
cycle in which the steam enters the turbine at 3 MPa and 350C and
is condensed in the condenser at 75 kPa. Determine the thermal
efficiency of this cycle and sketch an appropriately labeled T-s
diagram. Also compare this thermal efficiency to that a Carnot heat
engine operating between these same two limits.
The change in enthalpy across the pump = work done by the pump:
h2-h1= v1(P2– P1)
