WebFigure 3. Velocity and pressure profile in a control valve with choked flow and cavitation. Flashing. If we continue to decrease the downstream pressure, we reach a point where the pressure downstream of the valve is less than the vapor pressure of the liquid and we have the situation shown in Figure 4. Figure 4. WebFlow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve. Flow coefficient is an imperial measurement and is defined as: the flow of water through a valve at 60°F in US gallons/minute (gpm) at a pressure drop of 1lb/in². Flow factor is the metric equivalent of flow coefficient and is ...

WebJul 30, 2024 · Blood flow refers to the movement of blood through a vessel, tissue, or organ, and is usually expressed in terms of volume of blood per unit of time. It is initiated by the contraction of the ventricles of the heart. Ventricular contraction ejects blood into the major arteries, resulting in flow from regions of higher pressure to regions of ... WebCv for FLUIDS Cv for liquids is the volume of 68°F water in U.S. gallons per minute that passes through a valve at a pressure drop of 1 PSI. Flow for a given Cv is typically calculated from the following formula. Where: Q = Valve flow rate in gallons per minute (US GPM) ΔP = Difference between upstream and downstream pressure in WebThe flow coefficient - Cv - is based on the imperial units system and is defined as: the flow of water through a valve at 60 oF in US gallon/minute at a pressure drop of 1 lb/in2. … portland maine hockey game
