Test 3 Flashcards
The process of raising water from a static source to supply a pumper
drafting
Previously, battalion chiefs knew all available water sources in their districts and
captains in their response areas. They were known as
Pumper chances
During drafting operations, there is generally an elevation difference
between the static water source and the center of the pump. This
elevation difference is known as
Lift
Theoretically, at sea level a pump can lift water
33.8 feet (14.7 psi multiplied by 2.3 ft/psi)
For every 1,000 feet of altitude,
atmospheric pressure decreases by about
.5psi
The maximum height to which water can be drafted is closer to ___ feet, as opposed to the theoretical lift of 33.8 feet.
20- 25
At 20 feet of lift, the amount of water that can be supplied is only about ___ percent of the rated capacity of the pump.
60
The chosen site should allow ___-inches of water
completely around the strainer.
