______ pumper(also called the ______ pumper) is that pumper connected to the water supply at the beginning of the relay operation
Source pumper supply pumper
Source pumper should be the engine with the ____________________
Largest pumping capacity
Water supply may be a ________ or a _______ water supply source
Hydrant static
_____ pumper, sometimes referred to as the ________ pumper; receives water from the source pumper or another relay pumper, boost the pressure, and supplies the next pumper in the relay
Relay pumper in-line pumper
Hose tenders usually carry a _____or more of LDH (___" or greater)
Mile 4"
Smaller sizes of hose used for relay pumping include ___ to ___-inch hoselines. Generally ___ or _____ of these hoselines are laid
2 to 3 inch two or three
LDH ranges in size from ___ to ___inches, with ___ and ___inch being the most common sizes
3 to 12 inches 4" and 5"
Intake pressure relief valves, also called ______________
Relay relief valves
Two basic kinds of intake pressure relief valves: One is a integral part of the pump ___________. Second is screwed onto the _______________
Intake manifold pump intake connection
Intake pressure relief valves that are adjustable should be set within ___psi above the discharge pressure of the _________ pumper in the relay
10 psi previous
Relay pumping is based on two things:
-amount of water required at the scene -distance from the scene to the water source
If desirable to increase the amount of flow through a relay, one of three things will be necessary
-Increase size of hose or number of lines -Increase pump pressure of pumpers in the relay -Increase number of pumpers in the relay
Relay: pumpers increase their pump pressure, this does not necessarily mean that the _______ of water through the relay will be increased
Volume
Pumpers are rated to pump their max volume capacity at a net pump pressure of ____psi at _____.
150 psi draft
Max rated capacity from a static water source, if the pump operates at a pressure higher than ___ psi, volume capability of the pumper is ________
150 psi reduced proportionally
