The quality of the steam at the turbine exit
Webb12 apr. 2006 · 3,150. 16. JSBeckton said: A steam turbine has an inlet of 2kg/s water at 1000kPa and 350C and velocity of 15m/s. The exit is at 100kPa, 100% quality and very low velocity. Find specific work and power produced. I have done a lot of these problems but it usually says adiabatic or the inlet and exit temp is the same. WebbThe steam leaving the reheat section of the steam generator is at 5008C, and the condenser pressure is 6 kPa. If the quality at the exit of the second-stage turbine is 90%, determine the cycle thermal efficiency Question: 7 Steam at 10 MPa, 6008C enters the first-stage turbine of an ideal Rankine cycle with reheat.
