Can regeneration be done in pump gear?

A

No

P. 95

21
Q

If you ignore an empty DEF tank, that apparatus may be limited to what speed?

A

5mph

P.95

22
Q

What is the “Angle of Approach”?

A

Angle formed by level ground and a line from the point where the front tires touch the ground to the lowest projection at the front of the apparatus.

P.97

23
Q

What is the “Angle of Departure”?

A

Angle formed by the level ground and a line from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus.

P. 97

24
Q

What is the “Breaker Angle”?

A

Angle formed by level ground and the line from the point where the rear tires touch the ground to the bottom of the frame at the wheelbase midpoint.

P. 97

25
Q

At speeds above ____ MPH, an emergency vehicle may outrun the effective range of its audible warning device.

A

50mph

p. 101

26
Q

Increasing the speed of an apparatus by 20mph can decrease the audible distance by ____ feet or more.

A

250 feet.

P. 101

27
Q

How far apart should emergency emergency vehicles be when traveling the same route?

A

300-500 feet apart.

P. 101

28
Q

What is “Braking distance”?

A

Distance the vehicle travels from the time the brakes are applied until it comes to a complete stop.

P. 105

29
Q

What is “Total Stopping Distance”?

A

Sum of the driver reaction distance and the vehicle braking distance.

P. 105

30
Q

What is “Reaction Distance”?

A

Distance the vehicle travels while a driver transfers a foot from the accelerator to the brake pedal after perceiving the need for stopping.

P. 105

31
Q

If a building is less than five stories tall, where should the truck position?

A

Outside of the engine in relation to the building

P. 140

32
Q

If a building is more then five stories tall, where should the truck position?

A

Inside of the engine in relation to the building

P. 140

33
Q

What is a good tactic to keep the hose from kinking between the hydrant and engine?

A

Put a counterclockwise twist in the hose before connecting.

P. 144

34
Q

How far apart can engines be in tandem pumping?

A

up to 300 feet apart

P. 145

35
Q

What is the difference in relay vs tandem pumping?

A

Relay pumping is to increase the volume of water available at a fire scene.

Tandem pumping is to increase the water pressure.

P. 146

36
Q

Water volume increases to 1:_____ when converted to steam?

A

1,700 times its original volume

P. 169

37
Q

What are the 4 principles of Friction Loss?

A

1st = friction loss varies directly with the length of the hose or pipe

2nd = Friction loss varies approximately with the square of the increase in the velocity of the flow. ex. if flow is doubled, then friction loss is quadrupled

3rd = When flow remains constant, friction loss with decrease when the diameter of the hose in increased

4th = Friction loss is approximately the same, regardless of the pressure on the water

P. 178

38
Q

What is critical velocity?

A

When velocity of the water through a hose becomes so great that it becomes very agitated by resistance and flow is actually decreased. Leads to max length that hose line sizes can be flown at.

P. 181

39
Q

How often should valves within a water distribution system be tested?

A

at least once a year.

P.186

40
Q

What is the formula for calculated flow from a solid stream?

A

GPM = 29.7 x D squared x Square root of NP

P. 195

41
Q

What is the formula to calculate Nozzle Reaction for solid stream nozzles?

A

NR = 1.57 x D squared x NP

P. 203

42
Q

What is the formula to calculate Nozzle Reaction for fog stream nozzles?

A

NR = 0.0505 x Q x Square root of NP

P. 204

43
Q

What percent of forgiveness should flowmeters be accurate to?

A

plus or minus 3%

P. 282

44
Q

A flowmeter should be mounted _____ inches of the control valve and ____ inches from the pressure gauge?

A

6 inches and 2 inches

P. 282

45
Q

What is a positive displacement pump?

A

A self priming pump that uses a piston or rotors to move a given amount of fluid or air through a pump.

P. 295

46
Q

Centrifugal pumps are nonpositive displacement pumps. True or False?

A

True

P. 298

47
Q

What are the three parts to a centrifugal pump?

A

Impeller - Vaned circulating member that transmits motion to the water

Impeller Eye - intake office at the center of the pump

Volute - Spiral divergent chamber of a pump in which velocity of the water is converted into pressure
