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 ... WebMay 11, 2024 · When we have a 50% flow rate of 25 gallons per minute, the square root extractor output is 12 milliamps, or 50% as well. But, the Flow transmitter output is 8 milliamps or 25%. How do we convert 8 milliamps to 12 milliamps? Very simply, the square root extractor will ensure that its output is the square root of its input. The square root …

WebPressure does not rise linearly with flow rate; rather, it increases with the square of the flow rate: To write this as a proportionality, we relate flow rate ( Q) to pressure ( P) as follows (the constant k accounts for unit … Webon each side of the restriction measure the pressure differential caused by the fluid flow.
