Step 3 Determine the rate of heat transfer to the steam flowing through the reheater, in kW Question 19 Steam enters the first-stage turbine shown in the figure at 40 bar and 500°C with a mass flow rate of 110000 kg/hr. Steam exits the first-stage turbine at 20 bar and 400°C. The steam is then reheated at constant pressure to 500°C before entering the second-stage turbine. Steam leaves the second stage as saturated vapor at 0.6 bar. Assume steady state operation and ignore stray heat transfer and kinetic and potential energy effects. Steam + P₁ = 40 bar T₁, mi Wcv Turbine = P₂ = 20 bar T₂=400°C Reheater Turbine P3 = 20 bar T3 = 500°C 4 + Qreheater Determine the volumetric flow rate of the steam at the inlet to the first-stage turbine, in m³/min, the rate of heat transfer to the steam flowing through the reheater, in kW, and the total power produced by the two stages of the turbine, in kW. Step 1 Determine the volumetric flow rate of the steam at the inlet to the first-stage turbine, in m³/min. (AV) 1 m³/min Step 2 Determine the total power produced by the two stages of the turbine, in kW. kW Saturated vapor, P4 = 0.6 bar Power
