Q:
An oil cooler in a high performance engine has an outside surface area 0.12 m² and a surface temperature of 65 degree Celsius. At any intermediate time air moves over the surface of the cooler at a temperature of 30 degree Celsius and gives rise to a surface coefficient equal to 45.4 W/ m² K. Find out the heat transfer rate?
Answer & Explanation
Answer: B) 190.68 W
Explanation: Q = (T? – T?) A h = 0.12 (65-30) 45.4 = 190.68 W.
