A
steam power plant operates on the simple ideal rankine cycle. the
steam enters the turbine at 4 MPa and 500 C and leaves it at 50 kPa
and 150 C. the water leaves the condenser as a saturated liquid and
is subsequently displaced to the boiler by means of a pump at a
temperature of 85 C, which is the isentrophic efficiency of the
turbine?

In a power plant based on a simple Rankine cycle, steam
enters the turbine at 15 MPa and 900°C. The condenser pressure is 5

A steam power plant operates on a practical Rankine Cycle. The
steam enters the turbine at 3 MPa and “648” K and is condensed in
the condenser at a pressure of 46 kPa. You are assigned on a

A steam turbine is to operate on a simple regenerative cycle.
Steam is
supplied dry saturated at 40 bar, and is exhausted to condenser at
0.07 bar.
The condensate is pumped to pressure of 3.5 bar at which it is
mixed with
bleed steam from the turbine at 3.5 bar. The resulting water which
is at
saturated temperature is pumped to boiler. For the ideal cycle
calculate,
neglecting the feed pump work.

Rankine cycle operates on boiler pressure 15 MPa and condenser
pressure of 30 kPa. Superheated steam enters the high-pressure
turbine at 450°C. The high-pressure turbine expands the steam and
enters the re-heater at 2.5 MPa. The steam is reheated until
temperature reaches 450°C before being expanded in low-pressure
turbine to condenser pressure of 30 kPa. Assume the isentropic
efficiency of the low-pressure and high-pressure turbines are 94%
and 89% respectively, and pump is working isentropically. Neglect
the change in kinetic...
