WebNov 15, 2002 · Frequently the fluid flow Q through an orifice is assumed to be proportional to the square root of the pressure drop across the orifice Δ p. (1) Q=c d A 2 ρ Δ p sign ( Δ p) (In Eq. (1) cd denotes the discharge coefficient, A is the cross-section area of the restriction.) This formula strictly holds for an incompressible steady-state flow. As the incompressible steady-flow fluid passes through the orifice, pressure builds up due to flow restriction, causing the fluid velocity to increase according to Bernoulli’s equation.
