Requirement of Air Ventilators

1.	No. of Ventillators Reuired = Ventilation Rate Q/Exhaust Capacity
2.	Required Ventilation Rate Q (cfm) = Volume x Air Change Rate/60
3.	Volume of Spare to be Ventilated (ft³) = 1 x w x h
4.	Select Exhaust Capacity from Table B as per your required temp. Diff ^oC and Wind Velocity (MPH)
