Standard air is dry (0 percent relative humidity), 14.7 psia (101.4 **kPa**), and 60°F (15.5°C). The flow in a vacuum pipe is expanded cfm and represents the flow under actual vacuum conditions, referred to as actual cubic feet per minute (acfm), which is greater than scfm. Another phrase used to indicate acfm is inlet cubic feet per minute (icfm). One fire sprinkler can use on average eight **gallons-per-minute** (**GPM**). Most home fire sprinkler systems accommodate two simultaneous flowing sprinklers, with a minimum need of 16 **GPM** to supply them with water. The size of a house, local building requirements, and the water source may require more sprinklers or be required at a higher pump rate.

Formula: **GPM** x PSI x .0007 = horsepower needed Pump Output Flow (in **Gallons per Minute**) Pump RPM; Pump Displacement (in 3) Output Flow; Example: How much oil will be produced by a 2.5 cubic inch pump operating at 1200 rpm?. Psi : Psi is the abbreviation of pound per square inch , and is widely used in British and American Mega means million, therefore one MegaPascal equals 1,000,000 Pascals 3 **GPM** machine **kPa** to Psi **converter** to convert **kpa** to psi and vice versa Prince RD400 Series: No Prince RD400 Series: No. how do I determine **GPM** vs RPM so I When my pump runs at. Enter the hose diameter, hose length, **GPM** & press the '**calculate**' button to get the friction loss measured in PSI. **Calculator** Formula Printable Cheet Sheet Hose Diameter .75 inch 1 inch 1.25 inch 1.5 inch 1.75 inch 2 inch 2.5 inch 3 inch 3.5 inch 4 inch 4.5 inch 5 inch 6 inch. The C-value (l/ (s*bar)). Flow sonic conductance. Ratio of volume flow Q and input pressure p1 abs for choked flow C=Q/p1 abs. b. Critical pressure ratio. Ratio of output pressure p2 abs and input pressure p1 abs which marks the transition from choked flow (sonic velocity in narrowest section) to subsonic flow. kv.
