73
Q

percentage decrease in pressure formula

A

(static pressure - flow pressure) / static pressure x 100

74
Q

based on percentage decreased in pressure formula, percentage dictates how much water you have left to flow

A

0-10% decrease = 3 times current amount of water flowing
11-15% = 2 times
16-25% = 1 times
25% and greater = less than current amount flowing

difference in elevation between the surface of the static water supply and the center of the pump intake

116
Q

drafting
formula for maximum lift

A

L(height of lift in ft)=1.13(constant)xHg(inches of mercury)

117

A

1.57 x diameter squared x NP

136
Q

Impeller spins ____ times as fast as the engine

A

1.5-2.5

137
Q

Truck facing downhill, pull past or stop before building?

A

Pull past; uphill stop short

138
Q

If the pressure differential between compound and main discharge gauge is greater than ____ you cannot use the transfer valve without supplying more water to the pump

A

45psi

139
Q

Switching to volume step by step on a fire

A
  1. Notify IC that you will need to switch to volume and that there will be a drop in pressure to hose lines
  2. if there are interior crews, have them back out to a safe area
  3. Throttle down and close/gate down discharges (least important lines first)
  4. Confirm difference in pressure from compound and main discharge is less than 45 psi
  5. Switch to volume and then throttle up and open any gated down or closed discharges
