Steam enters the first stage of the turbine illustrated in the Figure below at 40 bar and 500 ºC with a volumetric flow rate of 90 m3/min. The steam leaves the turbine at 20 bar and 400 ºC. The steam is then reheated to a constant temperature of 500 ºC before entering the second stage of the turbine. The steam leaves the second stage as saturated steam at 0.6 bar. For a steady state operation and ignoring heat losses and the effects of kinetic and potential energy, determine: a) The mass flow of steam. b) The Power produced by turbine 1. c) The power produced by the turbine 2. d) The rate of heat transfer to the heater

Steam enters the first stage of the turbine illustrated in the Figure below at 40 bar and 500 ºC with a volumetric flow rate of 90 m3/min. The steam leaves the turbine at 20 bar and 400 ºC. The steam is then reheated to a constant temperature of 500 ºC before entering the second stage of the turbine. The steam leaves the second stage as saturated steam at 0.6 bar. For a steady state operation and ignoring heat losses and the effects of kinetic and potential energy, determine:
a) The mass flow of steam.
b) The Power produced by turbine 1.
c) The power produced by the turbine 2.
d) The rate of heat transfer to the heater.
