Question:

Water is the working fluid in a vapor power plant. Steam enters the turbine at 4 MPa, 540oC and exits the turbine as a two-phase liquid vapor mixture at 27oC. The condensate exits the condenser at 25oC. The turbine efficiency is 90% and the pump efficiency is 80%. If the power developed is 1 MW, determine
(a) The steam quality at the turbine exit,
(b) The thermal efficiency (ηth).
(c) The mass flow rate
