A swine nursery building is being designed to hold 300 pigs weighing 50 pounds each. Water vapor production in the building (from animal respiration and evaporation from wet surfaces) is expected to be 40.2 lbs H2O/hr. Outside air at 30 degrees F dry bulb and 50% RH is to be blown through a fan into the building. The air inside the building is to be at 65 degrees F dry bulb and 70% RH. Find A) Volumetric flow rate (cfm) of air that the fan should move to remove moisture from the building, and B) The rate at which heat (BTU/hr) will be removed from the building in the ventilation air.
