Poultry House Leakage Area Calculator 2014

This spreadsheet allows the user to determine the amount of leakage area a poultry house has by conducting a static pressure test.  A static pressure test consists of closing all the openings in a poultry house and then turning on one fan (typically that has an air moving capacity of roughly 0.75 to 1.25 cfm per square foot of floor space) and measuring the resultant level of static pressure achieved.

Inputs:

  • House length and width
  • The air moving capacity...
