Question

Newton law of cooling in lumped heat analysis

Answer 1

Newton's law of cooling states that 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 same.

Answer 2

Heat transfer version of the law. Theheat-transfer version of Newton's law, which (as noted) requires a constantheat transfer coefficient, states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings.
