It exits at 20 kPa (0.2 bar) with 93 percent quality, and velocity of 40 m/s. Assume potential energy change is negligible. Determine (i) The specific enthalpy of the steam entering the turbine & leaving the turbine. (ii) The change in kinetic energy per kg. (iii) The power output. (iv) The turbine inlet area. (v) What will be the effect of increasing mass flow rate of the steam on the power output? (vi) What is the implication of the Continuity equation in the SFEE.
