How To Calculate PPR Pipe Flows

The design of piping system materials and select the size of the pipe, brass filter piping systems and streaming media compatible for the application to provide the best overall economy. A larger pipe size could cost more initially, it provides a better operating efficiency, it can represent a quick return. One of the best ways to optimize the investment of pipe flow may be unnecessary operating costs of the expansion of the pressure loss on the basis of calculation of the actual pipe flow rate.

1Define pipe applications. Industry, as well as applications need to inject 425 gallons per minute (GPM) of water 575 feet underground reservoir, 80 feet higher than the pump wells. If it is a 60 pounds (per square inch pounds) pump can calculate the minimum of Schedule 40 steel pipe size, flow and pressure limit.

2 Make sure that the 425 gpm flow pressure. The reservoir is 80 feet higher than the pump, the pumping pressure of 60 pounds to push uphill water will be lost. Divided by the of 80 feet/2.31 ft / lb to produce a static pressure loss of 34.63 pounds, minus 60 pounds of pump pressure, PPR pipe series leaves 25.37 psi to 425 gpm flow, driven by 575 feet pipeline.

3 per 100 feet of pipeline pressure dropped, because this is how to publish the pipeline data. The generation of value 25.37 psi/575 feet/100 feet = 4.41-the PSI per 100 feet of decline in 425 gallons.

4 Consulting announced pipeline pressure and flow data of the Schedule 40 steel pipe, select a potential pipeline size. 4 in. Schedule 40 steel pipe pressure loss flow chart shows the traffic of 476 pounds to 5.5 pounds loss.

5, calculation of flow loss of 4.41-PSI loss of 5.5 psi in the 476 gpm flow. brass valve flow changes in pressure loss of the square root is proportional to the square root of the extracted (to 4.41 psi/5.5 PSI), = 0.8018 = 0.895 multiplied by 476 gpm flow diverted to the output of 426.23 GPM square root, this is just 425 gallons.
