Question a cyclic steam power plant is to be designed for steam temperature at inlet of 360 and a cyclic steam power plant is to be designed for steam temperature at inlet of 360 and an exhaust pressure of 008 bar after isentropic expansion of steam in the turbine the moisture content at the turbine exhaust is not to exceed 15 Determine the maximum allowable steam pressure at the turbine inlet and calculate the rankine cycle efficiency for these steam conditions estimate also the mean temperature of heat addition

1) Define the term degree of reaction (R) in a steam turbine 2mks 2) Determine the thermal efficiency of a steam power plant (Rankine Cycle) the specific and hourly steam consumption for a 30 MW steam turbine operating at inlet conditions Pressure 60 bar and temperature 600 C The condenser pressure is 040 bar 9 mks
