Question

Suppose a heat pump has a stationary bicycle attachment
that allows you to provide the work instead of using an
electrical wall outlet. If your heat pump has a coefficient
of performance of 2.0 and you can cycle at a racing pace
(Table 15–2) for a half hour, how much heat can you
provide?
