HYDRAULICS ENGINEERING MANUAL EXAM

1 3/4" CGN - ANSWER Nozzle: 150gpm @ 75psi

PP = 75 + 15psi/50'

GPM= 150

100' = 100psi
150' = 115psi
200' = 130psi
250' = 145psi
300' = 160psi

EB w/ 1 1/8' SBT - ANSWER Tip: 265gpm @ 50 psi

PP = 50 + 10psi/50'

GPM = 265

100' = 70psi
150' = 80psi
200' = 90psi
250' = 100psi
300' = 110psi

EB w/ (1) HR - ANSWER Nozzle: 150GPM @ 50psi

PP = 50 + 5psi/50' + 30psi AL

GPM = 150

100' = 90psi
150' = 95psi
200' = 100psi
250 = 105psi
300 = 110psi

, Standpipe Operations - PP for 1 Bundle - ANSWER 135psi

Standpipe Operations - PP for 2 Bundles - ANSWER 145psi

Standpipe Operations - PP for 1 HR - ANSWER 120psi

Standpipe Operations - PP for 2 High-Rise - ANSWER 120psi

Standpipe Operations - Pump Pressure for HR "Doubled-Up" - ANSWER
185psi

Standpipe Formula - ANSWER PP = Standpipe Pressure (120) + EL

*EL is determined by which floor the hose is hooked up to, not where the
nozzle extends up to

Standard Pump Pressure - Fixed Monitor SBT - ANSWER 90psi

Standard Pump Pressure - Fixed Monitor Automatic Nozzle - ANSWER
135psi

Standard Pump Pressure - 1" hardline - ANSWER 150psi

Standard Pump Pressure - Sprinkler System - ANSWER 150psi

*Never to exceed 185psi unless specifically engineered for that pressure

2 1/2" CGN - ANSWER Nozzle: 250GPM @ 50psi

GPM = 250

PP = 50 + 5psi/50'

100' = 60psi
150' = 65psi
200' = 70psi
250' = 75psi
