35
Q

What are the abbreviations for friction loss formula?

A

FL= Friction loss in PSI
C= Friction loss coefficient
Q= GPM divided by 100
L= Hose length divided by 100

36
Q

A

5”= .08
2 1/2” = 2
1 3/4” = 7
1” = 150

37
Q

What is the friction loss formula?

A

FL= (q+q) x q

38

47
Q

What is the rule of thumb for pumping the hose reel?

A

Start at 100 PSI

48
Q

What is the rule of thumb for pumping the wildland pack hose lay?

49
Q

Safe Pumping Margin For: 1 3/4” and 2 1/2” hose?

A

Tested at 400 PSI so safe to pump to 350 PSI.

50
Q

Safe Pumping Margin For: 1 “

A

Tested at 300 PSI so safe to pump to 250 PSI

51
Q

Safe Pumping Margin For: 5”

A

Tested at 200 PSI so safe to pump to 150 PSI

52
Q

Safe Pumping Margin For: 5” (green/high pressure)

A

Tested at 300 PSI so safe to pump to 250 PSI.

53
Q

When pumping from a hydrant, what are the three things that drivers should notify dispatch of?

A

1) Unit designator
2) Location of the hydrant
3) If the hose lay blocks access to a rode so other units can be redirected.

54
Q

What is an apartment lay?

A

When a 1 3/4” line is being supplied by a 2 1/2” line.

55
Q

What is the friction loss rule for an apartment lay?

A

1 3/4” = 75 PSI + 6 PSI per 100 feet of 2 1/2” hose.

56
Q

What is the rule for pumping foam eductors?

A

Target of 200 PSI at inlet with no more than 600 feet of 1 3/4” hose to the nozzle. This is because you lose 6 PSI per 100 feet of 1 3/4” hose and the following rule applies:
If FL + EL > 40, then the foam eductor must be moved closer to the nozzle. This is because the back pressure generated by the FL and EL will defeat the creation of foam.

57
Q

When should a relay operation be used?

A

When 500’ or more of 5” supply line must be used.

58
Q

What are the three roles that a driver may need to assume when involved in a relay operation?

A

1) Supply Engine
2) Relay Engine
3) Attack Engine

59
Q

What are the general Pressures that should be requested during relay operations based on GPM?

A

GPM Needed 0-500- request 80 PSI
GPM Needed 500-1000- Request 120 PSI
GPM Needed > 1000- Request 150 PSI

60
Q

What is the standard pressure that should be used when supplying a sprinkler system if no other pressure is designated on the FDC connection?

61
Q

What is the pressure for supporting a standpipe operation?

A

110 PSI + 5 PSI per floor
Exception: if pressure reducing devices are in place, adequate pressure should be used to pump water to the buildings highest floor.
