Match each type of pressure with its correct description - Answers Head pressure - pressure caused by
the height of a water supply above the discharge point
Static pressure - available pressure at a discharge point without water flowing
Flow pressure - The forward velocity of water at the discharge point
Residual pressure - water pressure in a distribution system that is still available when a hydrant is
flowing
Normal operating pressure - water pressure in a distribution system during regular consumption
The best definition of water pressure is the - Answers Force of water per unit area
, When hose diameter remains the same, friction loss varies approximately with the square of the
increase in flow rate therefore, if gallons per minute triples - Answers Friction loss is nine times greater
Large diameter hoses are generally defined as holes with a diameter between - Answers 4 and 6 inches

opened
According to NFPA 1901, a discharge pressure relief valve must operate within - Answers 10 seconds
after discharge pressure rises 30 psi above the set level
When controlling pump valves, push-pull handles - Answers Can accurately control line pressure and be
locked into place.

tanker once the MWS apparatus has been positioned in the correct order - Answers Deploy and connect
the supply line
make the pump operational
open the tank to pump valve
prime the pump, if necessary
open the discharge valve slowly
Set the throttle to the required engine pressure
set the pressure relief valve or the governor
monitor gauges associated with pump operation and make decisions based on your departments SOP's
and experience
