MWS CORRECT EXAMS QUESTIONS AND
ANSWERS SET A+
✔✔When controlling pump valves, push-pull handles: - ✔✔Can accurately control line
pressure and be locked into place.
✔✔The pump who's rotor is mounted off-center is the: - ✔✔Rotary vane positive
displacement pump.
✔✔If using a multi-stage pump for pumping from an internal tank or a hydrant: - ✔✔The
SERIES/PRESSURE position gives you maximum pressure for a short period.
✔✔Identify four true statements about gravity dump systems. - ✔✔Gravity dumps rely
on natures gravitational pull to empty the water from the tank,
Manually opened valves on gravity dumps may require someone to climb to the top of
the MWS apparatus tank,
The valve on the gravity dump may be designed to open manually or remotely,
Gravity dumps usually employee eight-inch or larger round or square piping with a valve
that extends to the exterior of the apparatus.
✔✔As operations proceed during water shuttles, make and break personnel at the fill
site should monitor: - ✔✔Ground conditions.
✔✔For fill site operations to be successful, it is suggested that you use: - ✔✔A pumper
at a hydrant to fill the MWS apparatus
✔✔The most efficient method of transferring water between portable water tanks is to: -
✔✔Use jet siphons.
✔✔When it becomes necessary for the pump site operator to operate off its tank
because the portable tanks are empty then: - ✔✔The attack pumper should be notified
that water losses is imminent.
, ✔✔The basic goal of a multiple portable water tank operation is to keep: - ✔✔The tank
being drafted from full at all times.
✔✔To determine the total flow rate using the actual testing method: - ✔✔Divide the
amount of water dumped by the trip time.
✔✔To determine the handling time in a flow rate calculation, add the fill site time and
the dumpsite 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.
✔✔The key thing to remember when conducting an inspection of an MWS apparatus is
to: - ✔✔Be systematic.
✔✔The purpose of the priming device test is to: - ✔✔Evaluate how quickly the priming
device can create a vacuum to bring water through a pump to the discharge hose.
✔✔The total stopping distance is: - ✔✔The sum of the driver/operator reaction distance
and the MWS apparatus' braking distance.
✔✔Identify the four steps for passing through a straight section of a road or highway. -
✔✔Check for oncoming traffic. Maintain apparatus speed. Check the side and rear view
mirrors.
Check the side streets of roads
✔✔Identify four steps for completing a left turn with an MWS apparatus on a four-lane
highway. - ✔✔Check for oncoming traffic. Check to see if the side street or road is clear.
Activate left turn signal.
Safely make the turn.
✔✔You should never back and MWS apparatus: - ✔✔If you don't have at least one
spotter.
✔✔The condensed "Q" formula for a 3-inch hose line is: - ✔✔FL= Q2/5
✔✔To correct for lateral thrust wear on parts in the centrifugal pumps, the pump: -
✔✔Has water enter the impeller in both directions.
✔✔Identify three true statements about positive displacement pumps. - ✔✔Some piston
positive displacement pumps can pump water on the forward stroke and on the return
stroke.
There is a piston type and a rotary gear type.
Many positive displacement pumps have been replaced by the centrifugal pump.
✔✔A priming device works by: - ✔✔creating a partial vacuum.
