A combination of a heat engine driving a heat pump (see Fig. P5.114) takes waste energy at 50◦C as a source Q_w1 to the heat engine, rejecting heat at 30◦C. The remainder, Q_w2, goes into the heat pump that delivers a QH at 150◦C. If the total waste energy is 5 M_W, find the rate of energy delivered at the high temperature.
