Turbine Thermo Steam Velocity
Q: Steam enters a turbine with a velocity of 20 ms-1, a pressure of 3 bar, internal energy of 3500 kJ kg-1 and density of 1.7 kg ms-3. The steam leaves the turbine with a velocity of 30 m s-1, an internal energy of 2900 kJ kg-1, density of 0.7 kg m-3 and at a pressure of 1.2 bar. If heat is lost to the surroundings at the rate of 30 kW and the output power of the turbine is 5 MW, calculate :
(a) the enthalpy of the steam at entry and exit from the turbine
(b) the entry and exit areas of the turbine.
