Question

find the second law efficiency of the steam turbine operating steadily at initial pressure of 3 MP and initial temperature of 450 degrees celsius the final condition of steam at 0.2 mpa and 200 degree Celsius neglect the Kinetic and potential energy changes the heat loss for the steam turbine to the surrounding is to 50 kW assume the mass flow rate of steam is 7 kg/s​

Answer 1

The final conditions of steam at 0.2 MPa and 2000C . Neglect the kinetic and potential energy changes. The heat loss from ...

Answer 2

Answer:

second law efficiency is 78%
