Q/3

Q=GPM

32
Q

RELAY PUMPING

A 
EITHER MAX DISTANCE OR
CONSTANT PRESSURE (MAX VOLUME)
33
Q

MAXIMUM DISTANCE

A

2,050’ FOR 5” HOSE
PDP IS 185 FOR 4” 5” (200 FOR 2.5” 3”)
DIVIDE TOTAL LENGTH BY 2,050 ADD PUMPER FOR REMAINDER

34
Q

CONSTANT PRESSURE

A

750’ SECTIONS FOR 5” HOSE
PDP IS 175
GIVES YOU 1607 GPM

35
Q

MILE

A

5,280’

36
Q

Hand method 1 3/4”

A 
100=1x12
125=2x9
150=3x9
175=4x9
200=5x9
Good for 150 and above
37
Q

Hand method 2 1/2”

A 
100=1x1x2
200=2x2x2
300=3x3x2
400=4x4x2
500=5x5x2
38

A

Elkhart: 85 psi
Hose: 90 psi
175 total

40
Q

Rear cross lay

A

15/16: 50 psi

A

Elkhart: 85 psi
Hose: 112.5
197 total

44
Q

LIKE VOLUMES

A

0-10%: 3
11-15%: 2
16-25%: 1
MAINTAIN 20 PSI OR MORE AT INTAKE

45
Q

ENGINE PRESSURE/PUMP DISCHARGE PRESSURE

A 
EP/PDP=NP+THFL+AL+EP
NOZZLE PRESSURE
TOTAL HOSE FRICTION LOSS
APPLIANCE LOSS
ELEVATION GAIN/LOSS
46
Q

STANDPIPE

A

ALWAYS CALCULATE, 150 PSI IS JUST FOR SPRINKLERS

IF PRV CALCULATE BASED ON TOTAL HEIGHT OF THE STANDPIPE

47
Q

DROP 10 METHOD VS CQ2L

A

SAME FROM 160 TO 300 PSI

48
Q

Like Volumes First Digit Method

A 
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
49
Q

Booster line

A

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.

50
Q

LDH pressure rating

A

Tested at 200 psi equals 185 operating psi

51
Q

Condensed Q

A

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

52
Q

Connecting to an FDC

A

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).

53
Q

Hydrants

A

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
