WebSolved Examples for Heat Loss Formula. Q.1: Determine the total heat loss from the building whose area is 60 sq. m, the coefficient of heat transfer is 0.7 and the temperature difference is 25 ∘ C. Solution: Given, U = 0.7. A = 60. Substitute these values in the given formula, q = 0.7 x 60 x 25. Therefore, q = 1050 watts. WebPrinciples of Heat Transfer. Heat is transferred to and from objects -- such as you and your home -- through three processes: conduction, radiation, and convection. Conduction is heat traveling through a solid material.
