In a steam turbine system, suppose the value of ∆mH is constant (meaning, inlet and outlet conditions are maintained). From the energy balance equation, Qnet + Wnet = ∆mH + ∆KE + ∆PE or −0.1209 kW − 70 kW = ??̇? + 8.75 kW − 0.0068kW 1. What will happen to Wnet if there was no increase in kinetic energy, will the magnitude of Wnet increase or decrease?
