3. A well-insulated turbine at steady state develops 10,000 Hp when provided with a
steam mass flow rate of 110 Ibm/s. The steam enters at 300 psi with a velocity of 180
ft/s and exits as saturated vapor at 10 psi with a velocity of 400 ft/s. Neglecting any
potential energy effects, determine inlet temperature (°C).

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.
