Since 37.5 GPM is halfway between the two flow readings of 35 and 40 GPM, the interpolation will work out to about 0.707 of the way between 0.9 and 1.2 PSI loss (again the square function). QR = Flow-rate predicted at the desired residual pressure in GPM QF = Total test flow-rate measured during test in GPM (GPM measured from Hose Monster or Pitotless Nozzle) HR = Pressure drop from static pressure to desired residual pressure (Static – 20 psi [if 20 psi is the desired residual pressure]) Efficiency = 78%, 750 [GPM] × 125 [PSI] / (1714 × 0.78) = 70.12 HP, Flow Rate = 125,000 BBL/Day Formula: GPM x PSI x .0007 = horsepower needed 1 hp = 745.7 W; Example - Hydraulic Pump. Plan for approximately 1.75 GPM per square foot of surface area, assuming the middle of the ranges below. Horse Power Requirements (Minimum) Electric HP = (psi x gpm) / 1460 Gas Engine HP = (psi x gpm) / 1100 Q = Flow Rate in gallons per minute Example: How many horsepower are needed to drive a 5 gpm pump at 1500 psi? Ft. 135788 / SG: CFM / PSI: 229.16: CFM / Hd. Then select a pump based on flowrate and total head loss requirements. Example: What displacement is needed to produce 5 GPM at 1500 RPM? 300 square feet surface area = 80-112 GPM; 400 square feet surface area = 100-150 GPM; DE Filters. This company assumes no liability for errors in data nor in safe and/or satisfactory operation of equipment designed from this information. All you do is enter your specifications and click the update button to calulate total losses for the system. Gallons Per Minute = Barrels Per Day × .0292 GPM = BPD × .0292 Horsepower = Torque in Inch Pounds × (Revolutions Per Minute) ÷ 63,025 HP = ((Torque in Inch Pounds) × RPM) ÷ 63,025 1 US Liquid Gallon = 231 Cubic Inches 1 US Liquid Gallon = 231 Inches^3 1 US Liquid Gallon = 0.13368 Cubic Feet 1 US Liquid Gallon = 0.13368 Feet^3 BHP = Brake Horsepower in horsepower Calculate the HP, Flow Rate or Discharge, and Total Head using this simple online calculator. Formula: GPM x PSI x .0007 = horsepower needed. Psi. Q stands for flow rate in gallons per minute, 1714 is a conversion factor needed to yield HHP in terms of horsepower. 24 square feet surface area = 36-48 GPM; 36 square feet surface area = 54-72 GPM Lph. Power Zone Equipment welcomes your inquiry. C = A conversion factor depending on units of flow and pressure, Horsepower [HP] = Flow Rate [GPM] × Pressure [PSI] / (C × Efficiency), Flow Rate = 750 GPM Interpolating between 35 GPM and 40 GPM, the pressure loss computes to a value between 0.9 and 1.2 PSI loss per 100 feet of pipe. I want to calculate: Flow Rate or Discharge(Q) = gpm Total Head(H) = ft Water Horsepower(WHP) = HP Calculator ; Formula ; Water Horsepower is the … Psi. Pressure = 798 Hd.Ft. Fuel pump FLOW Forced Induction (Petrol) 0. Gallons per minute (GPM) Pounds/Sq Inch (PSI) Horsepower; Example: How many horsepower are needed to drive a 5 gpm pump at 1500 psi? Efficiency = 81%, 125,000 [BBL/Day] × 798 [Hd.Ft.] © 2020 Womack Machine Supply Co. All rights reserved. n = Efficiency expressed as a decimal SG = 0.75 The water horsepower of the pump is roughly equal to ∗ ∗, where H is the vertical distance the water travels in feet, Q is the flow rate in gallons per minute, and SG is the specific gravity of the fluid. Flow = Gallons Per Minute; Pressure = Pounds per Square Inch; Example: The input horsepower required for a pump that needs to provide 10 GPM at 1500 psi is: HP= (10 x 1500) ÷ 1714 = 8.75 HP; Calculated out this gives an input horsepower requirement of 8.75 horsepower. Fuel pump FLOW -NA (Petrol) 0. Lph @ 0. Fuel pump FLOW - Forced Induction (E85) 0. Fuel pump FLOW -NA (E85) 0. P stands for pressure, pounds per square in. Pressure = 125 PSI needed for a hydraulic pump? DE filters are a little rangy as well. GPM x PSI x .0007 (a 'rule-of-thumb' calculation) We have knowledgeable people ready to help in English, Spanish, Malay and Mandarin. 1714, HHorsepower Required to Drive Pump P = Pressure in pounds per square inch Lph @ 0. The horsepower required by a a pump with flow 20 gpm and 1500 psi increase in pressure can be calculated as P HP = (20 gpm) (1500 psi) / 1714 = 17.5 HP. Bar. How to calculate horsepower So the loss would be: / {( 135,788 / 0.75) × 0.81} = 680.2 HP. How much horsepower is needed to drive a 10 gpm pump at 2000 psi? Example: How much oil will be produced by a 2.5 cubic inch pump operating at 1200 rpm? Note that the equation above is for a pump with 100% efficiency - which in the practial life is never true. Call us today. HP = (Flow x Pressure) ÷ 1714. Bar. 0. Lph. 0. This calculator allows you to figure out the head loss for pump selection. Horsepower Required to Drive a Pump. Psi To Gpm Conversion Chart Written by Kupis on September 15, 2017 in Chart Fluid power formulas fluid power formulas sizing water supply lines gpm to psi conversion chart hoskin 1 5 inch friction loss chart Efficiency. Estimate horsepower from these values. Units: Value of C: GPM / PSI: 1714: GPM / Hd. Psi. Ft. 3960 / SG: Barrels per Day / PSI: 58773: Barrels per Day / Hd. Formula: 231 x GPM ÷ RPM = in3 per revolution. 10 x 2000 x .0007 = 14 horsepower, (c) Website Copyright Protected All Rights Reserved, Do It Yourself Home Built Log Splitter Design Plans.
