STANDPIPE
ALWAYS CALCULATE, 150 PSI IS JUST FOR SPRINKLERS
IF PRV CALCULATE BASED ON TOTAL HEIGHT OF THE STANDPIPE
DROP 10 METHOD VS CQ2L

Like Volumes First Digit Method
Static: 90; Residual 70 Take first digit of static (9) times multipliers 1 x 9 = 9 2 x 9 = 18 3 x 9 = 27 Compare change (20 psi) 0-9 is 1 like volume 10-18 is 2 like volumes 19-27 is 3
Booster line
Elkhart 3F
Min: 50 psi gives you 5 gpm, FL of 0.5 psi per 100’, 51 PDP. MINNIE mouse has the booster at the lowest because she’s weak. She uses the LACE of her skirt to make a LAW badge to look official.
Max: 115 psi gives you 65 gpm, FL of 65 psi per 100’, 245 PDP. the robot MAXIMILLION has the highest because he’s strong. He TIES minnie’s TAIL to a JAIL cell so he can take over. NOAH ROLLS two rhino’s like bowling balls to bash the jail and set her free.
Mod: 100 psi gives you 35 gpm, FL of 18 psi per 100’, 135 PDP. Dieter the MOD tries to make peace by offering DAISIES to minnie and MAIL to max becasue he’s a dumb robot. Max TIES the MAIL to Dieter who gets stuck to the jail again.
LDH pressure rating
Tested at 200 psi equals 185 operating psi
Condensed Q
Field method for 5”
(also 3 and 4”)
Q^2 / 15 = FL per 100’
Connecting to an FDC
You can break the plastic but if you hit the bolts horizontally, they should break right off which is cleaner.
Connect a hose to every input on the FDC manifold.
If swivel is frozen: 1) twist your hose the opposite way a bunch of times before connecting; 2) get a double male and double female from the rig
If clogged with trash or completely broken just go inside and connect to the FDC on the first floor (unless PRV, then it won’t work).
Hydrants
Class C - Red - > 500 GPM
Class B - Orange - 500 - 999 GPM
Class A - Green - 1,000-1,499 GPM
Class AA - Light Blue - 1,500 GPM or greater
The more important metric is intake pressure. That’s what dictates how many lines you can pull.
Water dept can boost pressure or gpm
