Psi To Gpm Conversion Chart Written by Kupis on September 15, 2017 in Chart Domestic water piping design how 1 5 inch friction loss chart piping design program energy models water treatment mat The flow rate of water in gallons per minute, or gpm, can be calculated with the help of the Bernoulli equation and careful unit conversion. If the pressure is known in pounds per square inch, or psi, at two locations along the pipe, then the Bernoulli equation can be used to determine the velocity of the water You cannot directly convert PSI to GPM. They are two different units of measure. PSI measures pressure, and GPM measures flow rate. However, if other variables are known, you can use Bernoulli's equation to indirectly make a conversion. The following assumes the flow is in a pipe and the pipe diameter is known
. Example: Input hp = 10 gpm x 1500 psi. 10 MPa x 145.0 = 1450 PSI: PSI (pounds / square inch) PSI PSI: atm bar MPa: 0.068 0.0689 0.00689: 100 PSI x 0.068 = 6.80 atm 100 PSI x 0.0689 = 6.89 bar 100 PSI x 0.00689 = 0.689 MPa: kp/cm 2 (kilopound / cm 2) kp/cm 2 kp/cm 2: bar MPa PSI: 0.981 0.0981 14.223: 10 kp/cm 2 x 0.981 = 9.81 bar 10 kp/cm 2 x 0.0981 = 0.981 MPa 10 kp/cm 2 x 14.223. VELOCITY TO GPM CONVERSIONS in standard wall pipes* Flow Velocity (ft/sec) x Factor (1 ft/sec) = GPM Typical HVAC Design Maximum Flow = 4 to 8 ft/sec Nominal Pipe Size GPM @ 1 ft/sec GPM @ GPM = Calculate Flow Rate from Voltage Output (0-10 VDC) GPM = * Approximation for water. ** Refer to calibration tag or certificate
For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. Or, multiply by 100000/6894.757 = 14.503774. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774 WATER FLOW THROUGH STEEL OR COPPER PIPE Steel or copper piping is generally sized for water flow that will result in a friction loss of approximately 2 feet of water per 100 feet of pipe length and a velocity of 7 feet per second or less. This chart indicates the flow in GPM that a pipe size can generally handle: Pipe Size GPM ½ Up to 1.5 ¾.

Many other converters available for free A well designed liquid flow system typically has pressure losses of 1 psi per 100 feet of equivalent pipe. To have a 10 psi differential, you would have to have two pressure gages in your system separated by 1000 feet of equivalent piping, and then factor in differences in elevation The water flow rate through the mainline is 18 GPM. Using a pipe pressure loss table we find that the PSI loss for 1″ SCH 40 PVC at a flow rate of 18 GPM is 8.12 PSI per 100′. Therefore: 8.12 x 23 / 100 = 1.87 PSI - to simplify, you can round up the value to 2 PSI loss (Note: PSI loss charts vary somewhat from each other
