CE Pump Operations

Terms in this set (16)

The two components that work together to produce an efficient water stream are?
A. Pressure and Elevation
B. Volume and Pressure
C. Friction loss and velocity
Volume and Pressure
The required volume of water must be the initial goal identified to determine the required pressure?
A. True
B. Falso
A. True
If pump discharge pressures are increased, a greater volume of water can be delivered. However?
A. No change will occur in the hose line
B. Hose lines become stiffer, but nozzle reaction remains the same
C. Hose lines will become stiffer and nozzle reaction will increase
D. Hose lines become easier to manage
C. Hose lines will become stiffer and nozzle reaction will increase
Match the following nozzle with the appropriate GPM:

Elkhart Brass Chief XD fog nozzle -

7/8 Smooth bore nozzle -

15/16" Smooth bore nozzle -

TFT automatic fog nozzle -

1 1/8" Smooth bore nozzle -
Elkhart Brass Chief XD fog nozzle - 175 GPM @ 75 PSI

7/8" Smooth Bore - 160 GPM @ 50 PSI NP

15/16" Smooth Bore - 185 GPM @ 50 PSI NP

TFT Automatic fog nozzle - 70-200 GPM Depending on pump pressure.

1 1/8" Smooth Bore - 265 GPM @ 50 PSI NP
What equipment on the engine helps pump operators identify the volume of water flowing from their engine?

A. Pump Discharge Pressure Gauge
B. Visual confirmation of effective hose streams
C. Elkhart Brass External Flow Meter
D. FoamPro Flow Meter
D. FoamPro Flow Meter
The Foam Pro Flow meter shows total flow from all discharges on the apparatus?

A. True
B. False
B. False
The volume of water flowing through hose lines determine the required pump pressure needed for effective hose streams?

A. True
B. False
A. True
The color of the fire hydrant will indicate the available flow provided by that hydrant?

A. True
B. False
B. False

The color of the hydrant only identifies the size of the main the hydrant is connected to. It will not indicate available flow rates for the hydrant.
The primary limitation to the fire pump on the engine is?

A. Weather
B. Water Supply
C. Limited discharges
D. Available pressure
B. Water supply
The water tank on the engine holds?

A. 1000 gallons
B. 500 gallons
C. 250 gallons
D. 750 gallons
B. 500 gallons
​
How many hose lines can be charged prior to connecting to a fire hydrant?

A. Only 1
B. As many as needed
C. 2 Regardless of hose size
D. 2, as long as it is only a 1 3/4 attack line and the booster line
A. Only 1
What does the pump operator need to pay attention to, to ensure they do not deplete their water supply?

A. The numer of hoses in operation
B. The flow meter
C. The pump intake pressure gauge
D. Whether or not they are pumping to master streams or handlines
C. The pump intake pressure gauge
If intake pressure drops too low, what can be done to increase your available water supply?

A. Switch the transfer valve to volume mode
B. Nothing
C. Open the water thief on the hydrant
D. Gate all lines down
C. Open the water thief on the hydrant
What is the pump's rated capacity?

A. 2000 GPM @ 150 PSI
B. 1500 GPM @ 100 PSI
C. 1500 GPM @ 150 PSI
D. 1000 GPM @ 150 PSI
C. 1500 GPM @ 150 PSI
It is possible for the pump to exceed its rated capacity when connected to a hydrant?

A. True
B. False
A. True
