a A heat pump is used to maintain the inside temperature of a house at 20◦C when the outside temper-ature is 30◦C. What is the minimum amount of work necessary to transfer 100 J of heat to the inside of the house? b The heat of combustion of gasoline is approximately 47.0 kJ/mol. If a gasoline engine operates between 1500 K and 750 K, what is the maximum height that 5.0 moles of gasoline can lift a 400 kg aircraft?

An ideal heat pump is used to maintain the inside of a house at 22◦C when the outside temperature is Tout. Assume the pump does work at the rate of 1500W. The house loses heat by conduction (through walls, windows, etc.) at a rate given by (Tin − Tout) × 650W/ ◦C (a) For what outside temperature would the pump have to operate all the time in order to maintain the house at 22◦C? (b) If the outside temperature is...

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...
