How is heat rate calculated

WebThe sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units as hs = cp ρ q dt (1) where hs = sensible heat (kW) cp = specific heat of air (1.006 kJ/kg oC) ρ = density … WebIn general, the amount of energy required to raise a unit mass of a substance through a specified temperature interval is called the heat capacity, or the specific heat, of that substance. The quantity of energy necessary to raise the temperature of a body one degree varies depending upon the restraints imposed.
