A device operates under steady-state, steady-flow conditions. The device receives 45.2 kW of heat, the mass flowing in contains 165 kW of energy, and the device produces 65.6 kW of power. Determine the rate of energy flowing out of the system with the mass flowing through the outlet.
Given: Steady-State, steady-flow, so dE/dt = 0;
Q?=45.2 kW; E?massflow,in=165 kW; W?=65.6 kW
What will be an ideal response?
dE/dt=Q??W?+E?massflow,in?E?massflow,out = 0
Solving,
E?massflow,out= 45.2 kW -65.6 kW +165 kW = 144.6 kW
