The results in a PSI drop (pressure loss) at the other end of the hose. Discharge pattern is fully adjustable from straight stream to full fog. PSI to GPM calculation 06-02-2000, 12:13 AM A good book for you guys to start with maybe the IFSTA Fire Streams manual. To calculate the friction loss, it is necessary to know the following: • the volume or quantity of water flowing (expressed in gpm) • the size of the hose • the length of the lay Friction loss is independent of pressure when the gpm remains constant in the same size hose. In 1994 the tank was replaced with a new Glass King 900 Gallon fiberglass tank. 5” 12 Plus 2. Calculate how many BTUs you need to heat a room or even a house with a wood-burning, pellet or gas fireplace, insert or stove. Since tankless water heaters supply endless hot water, you don’t have to worry about capacity, but instead, think in terms of water flow rate. Well yield is a sustainable rate of water flow, usually expressed in gallons per minute (gpm), that a well can draw continuously over an extended period. 8 gpm is the minimum flow allowed for the 4 head calculation. 75" hose is 15. 5 gallons of water should flow out each minute. Liters Per Second =. GPM is usually more important to contractors than PSI. This could take a whole 15 minutes. Wouldn't the GPM be the same as the 6" line without the 3" throat, just flowing faster? I'm sorry I don't have the talent (or money) to figure this out, and I appreciate your help.
