Flow through an orifice hysys

WebIn the second part of the experiment, compressible gas flow through an orifice was studied. An orifice is an obstruction meter used to determine the flow rate of a fluid. At the orifice, the diameter decreases to a minimum, so the velocity of the fluid reaches a maximum and the pressure reaches a minimum. Bernoulli’s equation (see Equation 2) WebDec 26, 2005 · The velocity of a gas flowing through an orifice or an equipment leak attains a maximum or sonic velocity and becomes "choked" when the ratio of the absolute upstream pressure to the absolute downstream pressure is equal to or greater than [ ( k + 1 ) / 2 ] k / ( k - 1 ), where k is the specific heat ratio of the gas.For many gases, k ranges …

Webq m = flow rate of the fluid through the orifice (kg/s) C = coefficient of discharge (often 0.65 for an orifice plate) β = d/D ε = expansibility factor (for gas only, for liquid epsilon = 1) D = pipe diameter (m) d = orifice diameter (m) ρ = fluid density upstream the orifice plate (kg/m3) ΔP = pressure drop through the orifice plate (Pa) WebAug 17, 2015 · I would guess there will be choked flow where the downstream pipe, that the orifice is in, ties into the main pipe. This plus frictional loses will put backpressure on the downstream side of the orifice. If this backpressure causes the orifice pressure ratio to exceed the critical pressure ratio, there will be subsonic flow through the orifice. real estate listings boston ma https://remaxplantation.com
