Jul 22, 2017 · This will give us a specifi heat capacity of 1.0007643BTU/lb.F and density of 62.414lb/Ft3. Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. Q = (16,649FT3/h x 62.414lb/ft3) x 1.0007643BTU/lb.F x (53.6F – 42.8F) Giving us a cooling capacity of 8,533,364BTU/h. see full calculations below.
