PURPOSE:To always keep the pressure and flow rate at a proper level respectively for a water distributing pipe network, by calculating the optimum control degree in a short time with a high-speed model calculat
Use this Calculator to Determine Water Pipe Pressure, Flow Rate, Velocity, Diameter, Elevation, Length, Fitting Losses, and Pump Head
If you need to check discharge pressures, you can attach a pressure gauge to a discharge outlet elbow. This may be necessary to verify that your on-board pressure gauge is functioning properly. Nozzle Evaluations As you can see, the flow meter and pressure gauge have a variety of uses when...
Apart from the water flow rate, the pressure loading applied onto the sample was also adjustable in this set up. The applied pressure might be set at a higher level for tight-fitted garment and at a lower level for loose-fitted garment. Preliminary experiments suggest that the applied pressure...
Clean pressurized air was produced by an Atlas Copco SF2 Oil-free air system (Atlas Copco Airpower n.v. B, Wilrijk, Belgium). A flow meter measured the flow rate (Global Quality Analytical Resources, Scantec, Sweden). Two pressure regulators were installed and set to operate at a maximum ...

Generally, the discharge pressure ranges from 20 to 80 psi depending on the equipment served and elevations. Conversely, over time circulating pump flow tends to decrease due to impellor degradation. For a long time, accurately measuring such large flows in the field was nearly impossible, but ...
As ice flows against the up-stream side on an obstacle, the effective normal pressure increases by an amount proportional to the rate of glacier flow against the obstacle. Effective normal pressure is also reduced in the lee or on the down-stream side of the obstacle (Figure 7). The ...
Supercavity technology is one of the key technologies for underwater high-speed vehicles as it can reduce their resistance and increase their speed. In this paper, the current development of numerical calculation in supercavitation flow is reviewed. Firs
