Air velocity drops greatly as the end of the duct run is reached. ... In order to convert the right side to “something per hour”, we need to multiply by 60 min/h: Btu/h = [(grains x ft3)/(min x lb)] x 60 min/h ... cfm is the airflow in cubic feet per minute. Δh is the change in enthalpy . Q T (Btu/h) = Q s + Q L. ................
