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.
a) Draw the system with labels and show the ideal and the
non-ideal cycle...

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...

Consider a steam power plant operating on the simple ideal
Rankine cycle. Steam enters the turbine at 15 MPa and 600°C. The
steam condenses in the condenser at 10 kPa. Use the EES software to
study the effects of the following cases on the cycle performance
and to sketch the T-s diagram for each case:
Plot the variation of the cycle thermal efficiency with the
turbine isentropic efficiency. Take the isentropic efficiency of
the turbine in the range 70% to...

A coal-fired power plant uses 400 ◦C steam to turn a turbine.
Afterwards, the steam is condensed at a temperature of 25 ◦C. If
the plant burns 1 million kg of coal in one hour, running at
maximum efficiency, what is the amount of work that could be done
by the turbine in that hour? (Coal contains 27 kJ of energy per
g).

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
kPa. The turbine operates adiabatically and has an isentropic
efficiency of 85%, and the pump also operates adiabatically and has
an isentropic efficiency of 80%. Determine
the work required to pump the water to the boiler in
kJ/kg of water flowing, and
the enthalpy of the water leaving the pump.

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.

Superheated steam at 20 MPa, 640°C enters the turbine of a vapor
power plant. The pressure at the exit of the turbine is 0.5 bar,
and liquid leaves the condenser at 0.4 bar at 75°C. The pressure is
increased to 20.1 MPa across the pump. The turbine and pump have
isentropic efficiencies of 81 and 85%, respectively. Cooling water
enters the condenser at 20°C with a mass flow rate of 70.7 kg/s and
exits the condenser at 38°C. For the...
