A steam turbine operates adiabatically at a power level of 3500 kW. Steam enters the turbine at 2400 kPa and 500oC and exhausts from the turbine at 20 kPa as saturated vapor. What is the flow rate of steam run through the turbine, and what is the turbine efficiency? Draw the process on the P-H diagram.

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
project to improve the thermal efficiency of this plant. a) Draw
the schematic of the plant and determine the thermal efficiency of
the practical cycle assuming that the efficiencies of pump and
turbine are 0.75 and 0.7, respectively. ( b) Draw a...

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?

A steam power plant operates on a regenerative Rankine cycle.
Steam enters the turbine at 6 MPa at 700 ºC and the condenser at 10
kPa. Turbine has isentropic efficiency of 85% and pumps have
isentropic efficiency of 90%. Steam is extracted from the turbine
at 0.6 MPa to heat the feedwater in an open feedwater heater. Water
leaves the open feedwater heater as saturated liquid.

Steam enters the high-pressure turbine of a steam power plant
that operates on the ideal reheat Rankine cycle at 6 MPa and 500°C
and leaves as saturated vapor. Steam is then reheated to 400°C
before it expands to a pressure of 10 kPa. Heat is transferred to
the steam in the boiler at a rate of 6*104 kW. Steam is
cooled in the condenser by the cooling water from a nearby river,
which enters the condenser at 7°C. Show the...

A steam turbine operates with steam at inlet conditions of 3.5
MPa and 3500 C. The exit stream leave the turbine is at 0.8 MPa and
is known to contain a mixture of saturated vapor and liquid. The
steam rate through the turbine is 1000 kg/h. A (negligible)
fraction of exit stream is bled through a throttle valve to 0.10
MPa and is found to be 1250 C. The measured output of the turbine
is 100 kW.

A steam turbine operates adiabatically with a
steam rate of 25 kg/s. Due to frication and mechanical reason, the
turbine operates irreversibly. The steam at inlet
of the turbine is at 1300 kPa and 400 oC and discharges at 40 kPa
and 100 oC.
(1) What is the power output of the turbine?
(2) Calculate the efficiency of the turbine (adiabatically
irreversible) in comparison with a turbine that operate reversibly
and adiabatically from the same initial conditions (1300 kPa and...
