A device, including a heat engine and a heat pump, will be designed to deliver energy to a Heat Source as shown in Fig.Q3. It takes waste energy at 75°C as a source Qw1 to the heat engine rejecting heat at 30°C. The remainder Qw2 goes into the heat pump that delivers a QH at 235°C. If the total waste energy is 3 MW find the rate of energy delivered at the high temperature, QH.

Question

A device, including a heat engine and a heat
pump, will be designed to deliver energy to a Heat Source as
shown in Fig.Q3. It takes waste energy at 75°C as a source
Qw1 to the heat engine rejecting heat at 30°C. The remainder
Qw2 goes into the heat pump that delivers a QH at 235°C. If
the total waste energy is 3 MW find the rate of energy
delivered at the high temperature, QH.
