MWS CCRE -Questions & Answers 100% Correct
All of the following factors must be included when determining the total pressure loss (TPL)
EXCEPT: Correct-Pump pressure loss
The hand method can be used for estimating the friction loss in a hoseline with a diameter of:
Correct-2 1/2 inches
Large diameter hoses are generally defined as hoses with a diameter between: Correct-4-6
inches.
When a dry supply line is being charged, it is important to open the: Correct-Bleeder valve.
One of the drawbacks of a piston positive displacement pump is the: Correct-Fire stream
tends to pulsate.

NFPA 1901 requires that an MWS apparatus that uses medium diameter hose (MDH) supply
lines for filling should have at least ________ external fill connection (s) piped directly to the
tank: Correct-One.
Narrow roads Correct-Difficulty passing other vehicles and the possibility of getting the
apparatus tires off the road surface.
Long driveways Correct-When two apparatus approach from opposite directions, one may
be forced to back out.
Blind curves and intersections Correct-Driver/operator cannot see oncoming cross traffic
and drivers of non-emergency vehicles cannot see oncoming apparatus.
Winding roads Correct-Require a lot of concentration on the part of the driver/operator;
