An 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% open (x=0.7). Assume that the pressure drop across the valve remains constant.

This calculator may also be used to determine the appropriate pipe diameter required to achieve a desired velocity and flow rate. The following formula is used by this calculator to populate the value for the flow rate, pipe diameter or water velocity, whichever is unknown: V = 0.408 × Q/D2. V = Water Velocity; Q = Flow Rate; D = Pipe Diameter.

Spray Nozzle Flow Rate Calculator This calculator is meant to assist you with estimating the flow rate of a spray nozzle at pressures that aren''t listed in a catalog or if you do not have a catalog readily available. Many nozzle companies use a part number that describes the spray angle and flow rate at 40 PSI.

The Cv rating for each valve is listed in the tables found in the valve catalog. The definition of Cv is the # of gallons of water that will flow through the valve with a 1 PSI pressure differential when the valve is open. The equations below can be used to determine: Flow Rate, given the Cv and ΔP Cv, given the Flow Rate and ΔP

Flow Rate Calculator. Easily calculate the volumetric flow rate of a pipe (a.k.a. discharge rate) given its dimensions and either a pressure difference between its ends or the velocity of the liquid or gas flowing through it. The flow rate calculator can also calculate the mass flow rate of a fluid given its density is known. Input and output support metric and imperial measurement units.

They express coefficient Cv/Kv as the flow rate of water in g.p.m. [m3/h] for a pressure drop of 1 psi [1 bar] across a flow passage [flow coefficient: Cv-imperial, Kv-metric]. You can use the calculator to calculate maximum flow rate through control valve for given pressure drop and known flow coefficient of control valve Cv.

How Much Water Can Flow Through A Pipe (GPM/GPH)? We regularly get asked about the water flow capacity of different pipe sizes, and which is the best roof drain for a specific pipe size. Unfortunately, recommendations aren''t that straightforward because you also need to account for water pressure, material friction and more.

C V & FLOW CALCULATOR. This is our valve C v calculator. It allows you to calculate the flow or C v (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points in a network transporting a liquid or gas) and the flow rate. The use of this flow coefficient (C v) calculator leads to a standard calculation to …

Valve sizing calculator. The Kv-value is a measure of the flow rate through a valve for a given medium and pressure drop. The larger this value, the higher the flow rate through the valve will be at a given pressure drop. Usually, the Kv-value is given in the product description or datasheet.

2 giorni fa· The valve flow coefficient is the number of U.S. gallons per minute of 60°F water that will flow through a valve at a specified opening with a pressure drop of 1 psi across the valve. The coefficient is used to determine the size that will best allow the valve to pass the desired flow rate, while providing stable control of the process fluid.
