Determine the PDP for a siamesed layout in which there is an attack line of a 200-
feet with a 1 ¼-inch solid stream nozzle operating at 45 psi. The friction loss from
supply hoses is 30 psi. The friction loss from the attack hose is 25 psi. In addition,
there is an elevation gain of 40 feet between pump and nozzle. Total flow is 350
GPM. - correct-answer -A. 85 psi
B. 105 psi
C. 130 psi (Correct Answer)
D. 155 psi

TFL = NP + EP + APL
TFL = (45+30+25) + 20 + 10
TFL = 130
To Raise the temperature of one pound of water from 100°F to 212°F Takes -
correct-answer -A. 112 BTUs (Correct Answer)
B. 224 BTUs
C. 212 BTUs
D. 970 BTUs
Determine the approximate TPL for a hose assembly in which there is 500 feet of
a 4-inch supply line wyed into two, 2 ½-inch attack lines that are 200 feet long.
Each attack line is flowing 250 GPM. - correct-answer -A. 50 psi

B. 60 psi (Correct Answer)
C. 96 psi
D. 106 psi
FL (Supply Line) = C x (Q (Supply)/100)² x L/100
FL (Supply Line) = 0.2 x (500/100)² x 500/100
FL (Supply Line) = 0.2 x (5)² x 5
FL (Supply Line) = 0.2 x 25 x 5
FL (Supply Line) = 25
FL = 2 x (250/100)² x (200/100)
FL = 2 x (2.5)² x 2
FL = 2 x 6.25 x 2
FL = 25
TPL = FL + EP + APL
TPL = 50 + EP + 10

TPL = 60
Calculate the gpm flowing from a 1 3/4 inch solid master stream nozzle operating
at a nozzle pressure of 80 psi. - correct-answer -A. 801 GPM
B. 464 GPM
C. 813 GPM (Correct Answer)
D. 406 GPM
Q(Total) = 29.7 x (d)² x (√NP)
Q(Total) = 29.7 x (1.75)² x (√80)
Q(Total) = 29.7 x 3.0625 x 8.9442
Q(Total) = 813.53
