Calculate flow through valve with cv
WebSo following the above equation the Valve coefficient, Cv for liquids can be defined as the volume of water at 60°F that will flow per minute through a valve with a pressure drop of 1 psi across the valve. A C v value of a valve is 1 means a valve will pass 1 gallon per minute (GPM) of 60 o F water with a pressure drop (Dp) of 1 (PSI) across ... Webof Cv. For example, a Cv of 150 would then equate to 150 gpm of water at 60' F with a differential pressure of one psi. The formula below allows for calculation of flow rate …

WebAn equal percentage valve delivers 8 gpm of water when the valve is 50% open (x=0.5). When the valve is 60% open (x=0.6), the flow rate increases to 16 gpm. Estimate the flow rate through the valve when it is 70% …
WebA K v value is defined as the rate of flow of water in m 3 /hr and 4°C at a pressure drop of 1 bar across the equipment. K v relates to pressure drop and flow rate via the following expression: \displaystyle K_v = Q \sqrt { \frac {SG} { \Delta P}} K v = Q ΔP SG. Where Q is in m 3 /hr and ΔP is in bar. Thus for a given K v, ρ and Q the ... WebFeb 7, 2024 · We can calculate the flow through a valve using the following formula. Q = C v Δ P S G.
