WebThe orifice flow equation may be expressed as: The orifice flow equation yields the mass flow rate, or discharge Q, through an orifice, given the area of the orifice A. Q = Cd * A * √ (2 * g * H) Where, Cd = coefficient of discharge g = acceleration due to gravity in m/s^2 H = mean center line WebJul 24, 2024 · Substituting the value of A for the area of the orifice in the equation for fluid flow through an orifice, we can get an additional viscosity dependence part on the same equation. EDIT: This does depend on viscosity but this effect is lumped into the discharge coefficient. For an ideal orifice (i.e. without viscous dissipation), C=1. WebWeir and Orifice calculators are used to determine the inlet capacity in sag (ponding) condition to help choose the proper grate for your project. Below outlines the EJ equations used in our calculations. Orifice Equation Weir Equation Q= 0.0108A√d Q= Flow (CFS, cubic feet per second) A= Open area in grate (inches2 ) ireland to india currency
