A heat pump cycle operates between a geothemial reservoir and your house. The cycle requires 200 kW to operate with a coefficient of performance of 6. 7. Determine the hea transfer rate in and out of the cycle. Make sure to draw a picmie indicating where the cycle is in relation to the thermal reservoir and your house. Draw the heat transfer in and out and the net work on the cycle.
