Heat pumps are often used to heat houses in New Zealand. A typical setting for a heat pump might be 20 C (i.e., the room temperature). Normally, you expect the air to feel warm if you stand under the heat pump. On a particularly cold day, the air blowing out of the heat pump is at 26 C, and is at a velocity of about 1 m s-1. Using concepts of heat and mass transfer, briefly explain: i) why the heat pump can still heat the house to 20 C on this day ii) why it might feel like the heat pump is blowing cold air into the room if you stand underneath the heat pump.
