WebWith a change in temperature, the sensible heat formula is given as; Q sensible = 1.10 x cfm x (t o – t i) Q sensible = Heat gain from outside in Btu/h. 1.10 = product of heat capacity of air 0.018 Btu/oF. Cfm = rate of flow of air entering from outside. t … WebΔ E = q + w \Delta \text{E} = q + w Δ E = q + w. Where, E is internal energy. q is heat w is work. If energy is absorbed by the system (endothermic process), q has positive values …
