# Steam enters a closed feed water heater at 1.1 MPa and 200oC, and leaves as saturated liquid at the same pressure. Feed water enters the heater at 2.5 MPa and 50oC and leaves 12oC below the exit temperature of steam at the same pressure. Neglecting any heat losses, determine (a) The mass flow rate ratio. (b) The entropy generation rate
