_Qconv = h*_A*(_Ts-_Tc)

What is rate of convection heat transfer?

The rate of heat loss of a body is directly proportional to the difference in the temperatures between the body, and its surroundings, provided the temperature difference is small, and the nature of radiating surface remains the same. Despite the complexity of convection, the rate of convection heat transfer is observed to be proportional to the temperature difference. It is conveniently expressed by Newton’s law of cooling.
