The air-conditioner for a building transfers heat to the air outside the building via convection off the surface of its condenser. given the surface area of the condenser is 150 m2, the surface temperature of the condenser is 56°c, the outside air temperature is 32°c and the heat transfer co-efficient is 12 w/(m2.k) what is the rate of energy flow to the air by convection? work in base si units. state the units for your answer.
