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? What should be the sign of potential energy so that Wnet will increase in magnitude? 2. For a turbine system, what should happen to Qnet, ∆KE, and ∆PE to maximize the work done by the turbine? Which factor is the most significant?

Question
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? What should be the sign of potential energy so that Wnet will increase in magnitude?
2. For a turbine system, what should happen to Qnet, ∆KE, and ∆PE to maximize the work done by the turbine? Which factor is the most significant?
