Abstract
Pressure Interactions in Slotted Eave Inlets Pressure Interactions in Slotted Eave Inlets ABSTRACT Afull scale physical model eave opening and baffled slot inlet system for a mechanically ventilated livestock building was tested to determine the effect of pressure differences and attic opening size on air flow rates. Pressure differences were varied between the eave, attic and room of the model. Flow rates through the attic and the room, and corresponding pressure differences were measured to calculate loss coefficients. Closed attic tests that prevented interactions between the inlet and attic were conducted to develop regression equations to predict the coefficient of discharge (C^) and the loss coefficient (CJ. Linear regression equations fit the observed data very well and agreed with established theory. Open attic tests, with different sized attic openings, indicated that flow into the room was reduced compared to the closed attic case.
