Schedule 40-Steel Pipe Water Pumping
Define the steel pipe application. A industrial nicely application calls for pumping 425 gallons for just about every minute (gpm) water 575 feet away into an in-ground reservoir that’s 80 feet greater in comparison with pump inside the properly. In situation your 60-psi (pounds per sq inch) pump could be acquired, you may calculate the minimum Schedule 40-steel pipe size that may manage the flow and pressure constraints.
Decide stress obtainable to provide you together with the 425-gpm flow. Because the reservoir is 80 feet higher in comparison with pump, some inside the 60-psi pumping stress will most likely be lost pushing water uphill. Dividing 80 feet/2.31 feet/psi yields a static stress inadequate 34.63 psi, which, when subtracted inside the 60-psi pump stress, leaves 25.37 psi to push the 425-gpm flow although employing 575-foot pipe.
Scale stress drop per one hundred feet of pipe, considering that this is how printed pipe details are presented. Substituting values yields 25.37 psi/575 feet/100 feet = 4.41-psi drop per 100 feet at 425 gpm.
Consult printed pipe stress and flow information for Schedule 40-steel pipe to pick a attainable pipe size. Some-inch Schedule 40-steel pipe pressure-loss to circulate chart shows a loss of income of earnings of five.5 psi for nearly any 476-psi flow.
Calculate the flow getting a 4.41-psi loss while making use of 5.5-psi loss flow at 476 gpm. Due to the fact flow varies proportionately for that square explanation behind stress loss difference, extract the square purpose behind (4.41 psi/5.5 psi) = square explanation behind .8018 = .895 and multiply utilizing the 476-gpm flow reported to yield 426.23 gpm, that may only use 425 gpm.
Define the steam flow application. Saturated low stress steam at 12 psi is flowing through 3-inch Schedule 40-steel pipe. Whether or not it loses 1.five psi pressure inside the finish of one hundred feet inside the pipe, you are able to calculate the flow rate in pounds/hour (lb/hr) of steam.
Seek the advice of the Steam Flow Price and Pressure Drop for Schedule 40 Pipe chart (see Sources) to obtain the reference points for the 3-inch pipe. The Fir-psi drop flow worth reads 1,670 lb/hr in conjunction with the 2-psi value reads 2,400 lb/hr.
