The figure below shows a simple vapor power plant operating at steady state with water as the working fluid. Data at key locations are given on the figure. The mass flow rate of the water circulating through the components is 80 kg/s. Stray heat transfer and kinetic and potential energy effects can be ignored. Take T₁ = 543°C, T4 = 46°˚C, T5 = 21°C,and T6 = 43°C. - P₁ = 100 bar wwwww Steam generator Condenser P₁ = 100 bar Ţ₁ P₂ = 0.08 bar X₂ = 90% Turbine Pump Power in 4 2 S Determine the thermal efficiency (%).
