Average equilibrium airborne dust concentrations were predicted as a function of ventilation and dust generation rates. Time-dependent airborne dust concentrations at a designated location (or control volume) were also predicted from ventilation and dust generation rates. The model calculation, solved as a 3-D lumped form of control vol., represented conservation of air mass flow rate. Pig dust used in this project had an av. aerodynamic diam. of 2 mum, 95% of the dust particles were less than 5 um in diameter and approx. 45% of the particles were 2 um in diameter. Both ventilation rate and dust generation rate have a significant effect on airborne dust concentration. The lumped-parameter model is shown to be capable of predicting the ventilation rate required to maintain acceptable levels of airborne dust in animal housing. The accuracy of the model is influenced by the test dust particle size uniformity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pig dust was used as a test dust to verify a lumped-parameter model derived for predicting airborne dust concn at any location within a ventilated airspace.
