A pumper has 300-foot sections of three-inch hoses with 2 ½-inch couplings. They are
siamesed into a 200 toes of 5-inch attack line. The attack line that results in a master flow with a
flow of 350 GPM. Given this hose layout, decide the full stress loss for this hose meeting. -
ANS-A. 19 psi
B. 22 psi
C. 44 psi (Correct Answer)
,D. 78 psi
FL (Siamesed) = C x (Q/one hundred)² x (L/a hundred)
FL (Siamesed) = .2 x (350/100)² x (300/100)
FL (Siamesed) = .2 x (three.Five)² x three
FL (Siamesed) = .2 x 12.25 x 3
FL (Siamesed) = 7.35
FL (Attack 1) = C x (Q/a hundred)² x (L/one hundred)
FL (Attack 1) = .08 x (350/one hundred)² x (200/100)
FL (Attack 1) = .08 x (three.5)² x 2
FL (Attack 1) = .08 x 12.25 x 2
FL (Attack 1) = 1.96
TPL = FL + EL + APL
TPL = (7.35 + 1.96) + 0 + (10 [appliance] + 25 [master stream])
TPL = 9.31 + 0 + 10
TPL = forty four.31
A amount of 16.Sixty six pounds of water equals: - ANS-A. 16.Sixty six gal
B. Eight.33 gal
C. 6.Seventy eight gal
D. 2.0 gal (Correct Answer)
1 gal = 8.35 lbs
sixteen.66/8.35 = 1.Ninety nine
All of the subsequent are crucial reasons for maintaining inspection documentation on a
fireplace apparatus EXCEPT: - ANS-A. Providing proof throughout device coincidence
investigations
B. Verifying which you are inspecting the ideal apparatus (Correct Answer)
C. Providing evidence for guarantee and claims regarding the equipment
D. Determining whilst the device is due for replacement
All of the subsequent are capability water assets for an apparatus hearth pump EXCEPT: -
ANS-A. Pressurized water from a hydrant
, B. The onboard tank
C. Pressurized water from some other fire pump
D. A municipal hurricane drain (Correct Answer)
E. A swimming pool
All of the subsequent are rescue tools EXCEPT: - ANS-A. Spreaders
B. Extensions rams
C. Drills (Correct Answer)
D. Shears
All of the subsequent statements about driving a fire apparatus through regions of limited
horizontal and vertical clearances are true EXCEPT: - ANS-A. Use your side view mirrors
B. Make sure you can see your spotter
C. Judge your fireplace equipment' clearance round obstructions (Not Correct)
D. Use the precise turn sign
All of the subsequent statements approximately static resources are real EXCEPT: - ANS-A.
Pre-incident planning have to be finished to assess the accessibility of static waters sources
B. Weather can dramatically affect the accessibility and usefulness of static water resources
C. The static water assets that is closest to the incident have to be usually used first (Correct
Answer)
D. Safety of the equipment and crew is paramount whilst choosing a static water source
Allowing the fire equipment engine to idle over an extended time period can cause all of the
following EXCEPT: - ANS-A. Fuel Waste
B. Engine fatigue (Correct Answer)
C. Engine put on
D. Engine particles build-up
