Ahot engine generates excess heat at a rate of 7200 j per second. it has a surface temperature of 400°c, while its surroundings are at 27°c. the engine has a surface area of 0.45 m^ 2 and an emissivity of 0.75. the engine also loses heat via a steel conduit of diameter 44 cm and length 25 cm. assuming the temperature of the engine is stable, at what rate is heat lost to the surrounding air via convection?
