WebJun 8, 2024 · Flow rate is directly proportional to the square root of pressure. So for any given orifice, all else being equal, $\frac{GPM}{\sqrt{PSI}}$ is constant. Technically PSI here is the pressure difference across the orifice, but with no backpressure only the input pressure matters. For an orifice rated 1.8 GPM at 90 PSI, $\frac{GPM}{\sqrt{PSI}} = 0 ... WebThis calculator let you calculate the flow rate based on ISO 5167-2:2003 standard. This standard refers to the flow measurement with area reduction instruments, for circular pipes with the section completely filled with fluid.

WebSep 5, 2024 · Enter the pressure difference value across the orifice. Provide the actual mass flow rate through the opening. The calculator now has everything it needs to compute the coefficient of discharge and flow resistance. If you want to calculate the discharge coefficient using hydraulic head: Enter the diameter of the orifice if it is circular. WebOct 29, 2024 · The air flow through the orifices depends on: Orifice diameter; Air pressure; Coefficient of the orifice shape (For example, an orifice with a well-rounded entrance boasts a .98 coefficient. It will typically allow almost double the air flow as compared to an orifice with a sharp entrance, which has a coefficient of .53 to .61). WebMar 28, 2024 · The orifice flow calculator estimates the flow rate of liquid discharged from a tank through an orifice.
