WebThe pressure drop or the minor loss in a component correlates to the dynamic pressure in the flow and can be expressed as. Δp minor_loss = ξ p d = ξ ρ f v 2 / 2 (1) where . ξ = minor loss coefficient. p d = dynamic pressure in fluid flow (Pa (N/m 2), psf (lb/ft 2)) Δp minor_loss = minor pressure loss (Pa (N/m 2), psf (lb/ft 2)) WebAs water flows through the valve (restriction) a head loss (pressure drop) occurs. The magnitude of the head loss is related to the flow rate through the valve and the open area between the valve plug and the orifice through which the plug moves.
