MWS STUDY EXAMS GUIDE QUESTIONS AND
ANSWERS SET A+
✔✔All of the following are methods of water discharge used at the dump site EXCEPT?
- ✔✔draining
✔✔How much larger should a portable water tank used in a water shuttle operation be
than the water tank of the mobile water supply apparatus carrying it? - ✔✔500 gallons
✔✔The MOST efficient method of transferring water between portable water tanks is
to?? - ✔✔Use jet siphons
✔✔To determine the handling time in a flow rate calculation, add the fill site time and
the dump site time, including the time spent: - ✔✔To position the MWS apparatus at the
fill and dump sites, to make and break, and to fill and dump.
✔✔At a water shuttle operation, the amount of water dumped is the amount of water the
tank holds less? - ✔✔10%
✔✔Identify four of the steps for completing a left turn with an MWS apparatus on a four
lane highway. - ✔✔Activate the left turn signal
Check to see if the side street or road is clear
Safely make the left turn
Check for on-coming traffic
✔✔Identify THREE important reasons for knowing the dimensions of the MWS
apparatus you are driving? - ✔✔So you don't hit any obstructions
So you know whether it can travel under a specific overpass
So you are sure it will fit in a designated parking area
✔✔When performing a serpentine exercise, you? - ✔✔Should only travel in one
direction, without striking the obstruction.
, ✔✔All of the following are potential water sources for an apparatus fire pump EXCEPT?
- ✔✔Municipal Storm Drain
✔✔The best type of strainer to use in a shallow stream is a? - ✔✔Floating strainer
✔✔To determine the pump discharge pressure when supplying an attack apparatus,
you must add the total pressure loss to the? - ✔✔Required intake pressure of the
apparatus being resupplied.
✔✔1. Head Pressure
2. Static Pressure
3. Flow Pressure
4. Residual Pressure
5. Normal Operating Pressure - ✔✔1. Pressure caused by the height of a water supply
above the discharge point.
2.Available pressure at a discharge point without flowing water.
3. The forward velocity of water at the discharge point.
4. Water pressure in a distribution system that is still available when a hydrant is
flowing.
5. Water pressure in a distribution system during regular consumption.
✔✔Using the condensed Q formula, calculate the friction loss for 300 feet of 3 inch
hoseline, flowing a 300 gpm? - ✔✔27 PSI
Q=flow rate in hundreds of gpm
FL per hundred feet=Q2
✔✔Hard suction hoses are noted for their - ✔✔resistance to collapsing
✔✔When controlling pump valves, push pull handles? - ✔✔can accurately control line
pressure and be locked into place.
✔✔If using a multi stage pump for pumping from an internal tank or hydrant? - ✔✔The
SERIES/Pressure position gives you the maximum pressure for a short period.
✔✔Hazard/Danger Match
1. Narrow Roads
2. Long Driveways
3. Blind Curves and Intersections
4. Winding roads
5. Steep grades
6. Inclement weather - ✔✔Hazard/Danger Match
1. Difficulty passing other vehicles and possibility of getting the apparatus tires off the
road surface.
