In a single heater regenerative cycle steam enters the turbine at 30 bar, 3000C and condenser pressure is 0.096 bar. The feed water heater is a direct contact type which operates a direct contact type which operates at 5 bar. Draw flow and h-s diagrams considering the condition of steam at entry to the heater in mixture region. Calculate steam extracted from heater to turbine in kg per kg of steam flow the cycle and cycle efficiency. The enthalpies of steam at different locations of the cycle are given in a table below. Pump work may be neglected.
