The total power developed by a 20-stage reaction turbine is 15000 h.p. Steam is supplied at 15 kgf / cm2 absolute and at 300°C. The pressure of steam leaving the turbine is 0.1 kgf / cm2 abs. The turbine has a stage efficiency of 75% and a reheat factor of 1.05. Determine the mass flow rate of steam through the turbine. Assume that all stages develop equal power.
