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...

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 heavily insulated steam turbine operates steadily and is
supplied with 1 kg/s steam at 2MPa, 400 deg C. If the outlet
temperature is 100 deg C and the turbine has an output of 1000 kW
determine the quality of the outlet steam, the rate of entropy
generation and the isentropic efficiency of the turbine. (Changes
in kinetic and potential energy are negligible).

Steam enters a turbine at a rate of 550 kg/hr. The steam enters
the turbine at 28 atm and 350°C at a linear velocity of 55 m/s. The
steam leaves the turbine at a point 3.5 m below the turbine inlet
at atmospheric pressure and a velocity of 355 m/s. The turbine
delivers shaft work at a rate of 50 kW, and the heat loss from the
turbine is estimated to be 2250 kcal/hr.
What is the temperature of the...

A mass flow rate of 2 kg/s of steam is expanded in an adiabatic
turbine with an isentropic efficiency of 0.92. The steam enters at

A steam turbine receives 8 kg/s of steam at 9 MPa, 650 C and 60
m/s (pressure, temperature and velocity). It discharges
liquid-vapor mixture with a quality of 0.94 at a pressure of 325
kPa and a velocity of 15 m/s. In addition, there is heat transfer
from the turbine to the surroundings for 560 kW. Find the power
produced by the turbine and express it in kW
