1. The problem statement, all variables and given/known data A)What is the coefficient of performance of an ideal heat pump that extracts heat from 11∘C air outside and deposits heat inside your house at 30∘C? B) If this heat pump operates on 2000W of electrical power, what is the maximum heat it can deliver into your house each hour? 2. Relevant equations COP = QH/W COPideal = TH/(TH-TL) 3. The attempt at a solution TH = 30 + 270 = 300 TL = 11 + 270 = 281 COPideal = 300/(300-281) = 16 that part came up right for the second part W = 2000 J/s COP = QH/W QH = COP(W) = 16 (2000 J/s) = 32000 J/s 32000 J/s (3600 s/ h) = 115200000 J/h i rounded to 2 sig figs because thats what the question wanted but it was wrong. What mistake did I make?
