WebJun 26, 2009 · The sensible heat of the air is calculated as follows: SH = m*0.133*DBT. Where: m is the mass of the dry air, 0.133 is the specific heat of air in Kcal/kg and DBT is the dry bulb temperature of the air. From the above formula is clear that the sensible heat of the air depends on dry bulb temperature of the air and the mass of the dry air.
