WebFeb 7, 2024 · We can calculate the flow through a valve using the following formula. Q = C v Δ P S G Suppose we use water with a specific gravity of 1.0 and a constant for the Cv. We can see that, as the pressure delta (pressure difference in the upstream and downstream sides of the valve) increases, so does the flow. WebWhen the gas velocity is choked, the equation for the mass flow rate in SI metric units is: where the terms are defined as in listed below. ...

By assuming steady-state, incompressible (constant fluid density), inviscid, laminar flow in a horizontal pipe (no change in elevation) with negligible frictional losses, Bernoulli's equation (which expresses the conservation of energy of an incompressible fluid parcel as it moves between two points on the same streamline) can be rewritten without the gravitational potential energy term and reduced to: Webchoked (when it sees sonic velocity in the valve orifice). In the above equation, x = ΔP/P1 (Note: P1 or P2 is always absolute pressure, i.e., gage psi plus 14.7) Fk =the ratio of the specific heat k of a gas (air = 1.4), Fk = k of gas/1.4 XT = pressure drop ratio. This is the ΔP/P1 at which there is no longer any flow increase.
