(\Delta P) in kPa, (L/G) in L/m³, (v_t) in m/s. The efficiency for a given particle size: [ \eta = 1 - \exp\left[ - \fracQ_g

[ \Delta P = 2.5 \times 10^-3 \times \left( \fracLG \right) \times v_t^2 ] (L/G) in L/m³

An is a practical tool for these calculations, allowing engineers to vary inputs and instantly see effects on performance. Key Design Parameters Before building the spreadsheet, define these inputs:

[ \Delta P = 0.44 \times \left( \fracLG \right) \times v_t^2 ]

[ D_t = \sqrt\frac4 A_t\pi ] Most Venturi models use Calvert’s equation (for particulate removal):
