A closed system receives 15.0 kW of power while losing 8.2 kW of heat at one instant in time. Determine the time rate of change of the energy of the system at that instant.
Given: Closed system (so no energy change from mass flow); Q?=?8.2 kW; W?=?15.0 kW
What will be an ideal response?
Solution: dEdt=Q??W?= -8.2kW – (-15.0 kW) = 6.8 kW
