15 psi

NP

Desired or designed nozzle pressure for the nozzle being used

50 PSI plus the friction loss

Example: the forward pumper is pumping 200psi. How much PSI does the key pumper need to give.

((GPM x HS)/10) - 10) = FL/100'

Friction loss formula

((100 x 3(HS value for 1 3/4")/10)-10 ; (300/10)-10 ; 30-10=20 ; 20 x 1.5(150ft of hose) = 30

GPM = 100 ; HS = 1 3/4" ; 150ft

((125 x 4(HS value for 1 1/2") / 10) - 10 ; (500/10) - 10 ; 50 -10 = 40 ; 40 x 1.5 (150 feet) = 60 FL

GPM = 125 ; HS = 1 1/2" ; 150 ft

((150 x 3 (HS value for 1 3/4") / 10) - 10 ; (450/10) - 10 ; 45 - 10 = 35 ; 35 x 2 (200 ft of hose) = 70 FL

GPM = 150 ; HS = 1 3/4" ; 200 ft

((200x 1(HS value for 2 1/2") / 10) - 10 ; (200/10)-10 ; 20-10 = 10 ; 10 x 3 (300 ft) = 30 FL per 100 ft of hose

GPM = 200 ; HS = 2 1/2" ; 300ft

((200 x 2(HS value for 2") / 10) - 10 ; (400/10)-10 ; 40-10= 30 ; 30 x 2(200 feet of hose) = 60

GPM = 200 ; HS = 2" ; 200ft

((95 x 4(HS value for 1 1/2") / 10) - 10 ; (380/10)-10 ; 38-10= 28 ; 28 x 2(200 feet of hose) = 56 FL per 100' of hose

GPM = 95 ; HS = 1 1/2" ; 200ft

Intake to intake

Single

Multiple hand lines- Engine pressure is the highest ___________ line

95

Penetrating nozzles produce _____ GPM

(PSI drop x 100) / Static pressure = % drop

Percent method formula

25

Portable monitor multiple inlet ________ PSI

FL

Pressure lost as water travels through hose, fittings, appliances, piping, and adapters?

Head

Pressure produced as water moves downhill is ______ pressure.

Back

Pressure pushing back against the pump while trying to move water uphill is ______ pressure.

1/2 = 4/8 ; 4 + 2 = 6 ; 6 x 100 = 600 GPM

Rule of Eights Example: 1 1/2" tip

3/4 = 6/8 ; 6 + 2 = 8 ; 8 x 100 = 800 GPM

Rule of Eights Example: 1 3/4" Tip

1 8/8 ; 8 + 2 = 10 ; 10 x 100 = 1000 GPM

Rule of Eights Example: 2" Tip
