Question 49

Booster line

Answer 49

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.

Question 50

LDH pressure rating

Answer 50

Tested at 200 psi equals 185 operating psi

Question 51

Condensed Q

Answer 51

Field method for 5" (also 3 and 4") Q^2 / 15 = FL per 100'

Question 52

Connecting to an FDC

Answer 52

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).

Question 53

Hydrants

Answer 53

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
