How do I find out what Gallons Per Minute (GPM) this pump is capable of?(Plunger Radius X Plunger Radius X 3.142) = Sq. Inches of Circle (Sq. Inches of Circle) X (Stroke Length) X (Number of Plungers) = Cubic Inches of Liquid Per Revolution Cubic Inches of Liquid Per Revolution / 231 = Gallons Per Revolution (Gallons Per Revolution) X (Max RPM) = Gallons Per Minute NOTE: Max RPM in the above equation varies according to type of pump, size of stroke, and other variables. Duplex pumps often run about 100 RPM Max. while triplex pumps will run somewhere between 100 RPM Max and 400 RPM Max.</p> <p>I have a reciprocating pump and I know what my max rated rod load is (in foot pounds). I also know what size plunger size my pump has. What PSI will my pump produce?Max. PSI = Rod Load Rating of Pump / (Plunger Radius X Plunger Radius X 3.142)</p> <p>http://www.powerzoneequipment.com/pump-calculator-formulas-and-equations.asp</p> <p>21/12/2010 10:15:05 </p> <p>Pump Calculations, Pump Equations</p> <p> 2</p> <p>I have a reciprocating pump and I know what my max rated rod load is (in foot pounds). I also know what PSI I need. What size plungers do I need?Min. Plunger Size Needed = Square Root of (Rod Load Rating of Pump / Max. PSI / 3.142)</p> <p>Formulas for Centrifugal Pumps</p> <p>I know what maximum PSI and maximum GPM I need. What size pump do I need?Centrifugal Pump Formula: Minimum Horsepower Required = ((Max GPM) X (Max PSI) / 1710) / (Efficiency in Percentage) X (Specific Gravity of Material)</p> <p>How do I calculate PSI (Pressure in Pounds Per Square Inch) or TDH (Total Dynamic Head)?Assuming you have one measurement for your pump but not the other: PSI = TDH / 2.31 TDH = PSI X 2.31</p> <p>How do I calculate Brake Horsepower Required for a centrifugal pump?Brake Horsepower Required = GPM Required X (Total Dynamic Head) / 3940 / Efficiency</p> <p>General Equations(1) Barrel = 42 gallons Gallons Per Minute = Barrels Per Day X .0292 GPM = BPD * .0292 HorsePower = Torque in Inch Pounds X (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 1 US Liquid Gallon = 3.78541 Liters 1 Liter = 0.26417 US Liquid Gallons 1 Cubic Foot = 7.84 US Liquid Gallons 1 Foot^3 = 7.84 US Liquid Gallons 1 Cubic Foot = 28.31685 Liters 1 Foot^3 = 28.31685 Liters Cubic Feed Per Day = Cubic Feet Per Minute X 1440 Feet^3 Per Day = (Feet^3 Per Minute) * 1440 Cubic Feet Per Minute = Cubic Feet Per Day Divided by 1440 Minutes Per Day Feet^3 Per Minute = (Feet^3 Per Day) / 1440 Minutes Per Day</p> <p>Chart of Relative Density / Specific Gravity for Common LiquidsSpecific Gravity is used when sizing a centrifugal pump. Liquids with a specific gravity greater than 1.0 are heavier than water and conversely, liquids with a specific gravity lower than 1.0 are lighter weight than water and will generally float on water.</p> <p>http://www.powerzoneequipment.com/pump-calculator-formulas-and-equations.asp</p> <p>21/12/2010 10:15:05 </p> <p>Pump Calculations, Pump Equations</p> <p> 3</p> <p>Material Alcohol, ethyl (ethanol) Alcohol, methyl (methanol) Alcohol, propyl Butane, liquid Crude oil, California Crude oil, Mexico Crude oil, Texas Ethane Ethylene glycol Gasoline, Natural Gasoline, Vehicle Kerosene Methane Octane Oxygen Propane Propane Water, pure Water, sea</p> <p>Degrees Celsius 25 25 25 25 15.56 15.56 15.56 -89 25 15.56 15.56 15.56 -164 25 -183 -40 25 4 25</p> <p>Degrees Fahrenheit 77 77 77 77 60 60 60 -128.2 77 60 60 60 -263.2 77 -297.4 -40 77 39.2 77</p> <p>Specific Gravity 0.787 0.791 0.802 0.601 0.918 0.976 0.876 0.572 1.100 0.713 0.739 0.820 0.466 0.701 1.14 0.585 0.495 1.0 1.025</p> <p>Sitemap | Feedback/Comments/Complaints Oil Field Equipment - Centrifugal Pumps - Paristaltic Pumps - Piston Pumps - High Pressure Pumps - Mud Pumps Positive Displacement Pumps - Plunger Pumps - Triplex Pumps - Reciprocating Pumps Duplex Pumps - Drilling Mud Pumps - Oil Field Pumps 2007 Power Zone Equipment | Layout &amp; Graphic Design by Schweb Design 2010 Power Zone Equipment | Dynamic Content, Search, Seo, and Additional Layout Programmed by the IT Department at Power Zone Equipment, Inc.
