WebSep 7, 2010 · The geometry of the flow path has a direct bearing on the flow. For a converging/diverging nozzle, the choked plane forms at the minimum flow area. For example, in an isentropic flow in a De Laval nozzle, the critical pressure ratio is given by: (1) For air, with γ = 1.4, the critical pressure ratio is 0.528 and for steam (γ = 1.3), 0.546. WebThe calculator determines the control valve flow coefficient (Cv) required to pass a specified flow rate given the upstream and downstream pressure of the control valve, the fluid properties, the valve pressure drop ratio factor and the pipe geometry factor. Webp = pressure (Pa, psf (lb/ft2)) ρ = density (kg/m3, slugs /ft3) v = flow velocity (m/s, ft/s) The equation can be adapted to vertical flow by adding elevation heights: p1 + 1/2 ρ v12 + γ h1 = p2 + 1/2 ρ v22 + γ h2 (1b) where γ = … theaterstrasse 22
