A pumper has two 300-foot sections of 3-inch hoses with 2 ½-inch couplings. They are siamesed into a 200 feet of 5-
inch attack line. The attack line that ends in a master stream with a flow of 350 GPM. Given this hose layout,
determine the total pressure loss for this hose assembly. - Correct Answer A. 19 psi
B. 22 psi
C. 44 psi (Correct Answer)
D. 78 psi
FL (Siamesed) = C x (Q/100)² x (L/100)
FL (Siamesed) = .2 x (350/100)² x (300/100)
FL (Siamesed) = .2 x (3.5)² x 3
FL (Siamesed) = .2 x 12.25 x 3
FL (Siamesed) = 7.35
FL (Attack 1) = C x (Q/100)² x (L/100)
FL (Attack 1) = .08 x (350/100)² x (200/100)
FL (Attack 1) = .08 x (3.5)² x 2
FL (Attack 1) = .08 x 12.25 x 2
FL (Attack 1) = 1.96
A quantity of 16.66 pounds of water equals: - Correct Answer A. 16.66 gal
B. 8.33 gal
C. 6.78 gal
D. 2.0 gal (Correct Answer)
1 gal = 8.35 lbs
16.66/8.35 = 1.99

D. Use the appropriate turn signal
All of the following statements about static sources are true EXCEPT: - Correct Answer A. Pre-incident planning must
be done to assess the accessibility of static waters sources
B. Weather can dramatically affect the accessibility and usability of static water sources
C. The static water sources that is closest to the incident should be always used first (Correct Answer)
D. Safety of the equipment and crew is paramount when choosing a static water source
