What is the Formula for Engine Pressure Calculations? -
ANSWER-DP(discharge pressure)=NP(Nozzle Pressure)+FL
(Friction Loss)+AFL (Appliance Friction Loss)+ Elevation
In a Relay operation how much Pressure should relaying pumper
make sure the receiving pumper is getting? - ANSWER-Maintain
20 psi for receiving pumper
How do you calculate FL(Friction Loss) for multiple lines of same
size? - ANSWER-Just figure out PSI for one line and same goes
for wye and siamese operations you just figure out one side but
don't forget to make sure you figure out correct GPM for the line
you are calculating FL for.
Pressure Governor - ANSWER-Works by regulating the power
output of the engine (RPM) to maintain set pump discharge
pressure.

When excess pressure builds up, a tube from discharge side of
the pump transmits the rise to a governing device, which cuts
back the throttle.
Governing devices very with each manufacturer's design.
Intake Relief Valve - ANSWER-Protects intake side of pump
Water hammer
Dumps excess to the ground
Master Drain - ANSWER-Uses of the master drain:
-Drain the main pump housing (1st & 2nd stages)
-Drain the tubing to pump panel gauges
-Drain the auxiliary cooler.
-Transfer valve
DO NOT OPERATE WHILE PUMP IS OPERATING!
Bleeders - ANSWER-Located on gated intakes (5" intake relief
valve). This is to bleed air off as a supply line is charged before
the gated intake is opened.

Auxiliary Cooler - ANSWER-Continuous copper tubing from
discharge to intake side of the pump
acts as a heat exchanger
water does not mix with radiator water
open slowly
loss of anti-freeze/cracked tubing
normal operating temp. 160 to 180 degrees
Cooling Alternatives - ANSWER-Open Hood
Use exhaust fans
Spray radiator (diesel only)
Operate cab heater
Radiator Filler - ANSWER-Small line from discharge side of pump
used in emergency to add water to radiator
open SLOWLY!!

4 Basic Flowmeters - ANSWER-Differential
Turbine
Paddlewheel
Spring Probe
What does one cubic foot of water weigh? - ANSWER-62.5 lbs
What does One cubic foot of water contain in inches? - ANSWER-
