A hose has a flow rate of 50 gpm with a friction loss of 2 psi. If the flow rate increases to
200 gpm, then the friction loss will increase to: - ANSWER-A. 32 psi (Correct Answer)
B. 24 psi
C. 16 psi (Not Correct)
D. 8 psi
GPM is 16 times greater = 2 x 16
A major advantage of small diameter hoses is their: - ANSWER-A. Use as supply lines
B. Use in drafting from static water supplies
C. ease of relocation and movement (Correct Answer)
D. Inflexibility, allowing fire apparatus to drive over them

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. - 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
TPL = FL + EL + APL
TPL = (7.35 + 1.96) + 0 + (10 [appliance] + 25 [master stream])
TPL = 9.31 + 0 + 10
TPL = 44.31
A quantity of 16.66 pounds of water equals: - 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
