Define both the constant, y, and the exponent ,z, for q in the Hazen-
Williams friction loss formula shown Below:
P = L x (y x Q^z)
(c^1.85 x d^4.87) - ANSWER-4.52, 1.85.
Reference NFPA 13 2016 Section 23.4.2.1.1.
A water flow test was conducted using 1 hydrant, flowing with two 2 1/2
inch outlets. Which is the approximate water flow rate, if the pitot
reading was 15 psi. The hydrant outlet coefficiant is 0.8. - ANSWER-
The correct answer is 1156 gpm.

Q 1 = 29.84 cd 2 √ P
Q 1 = 29.84 x 0.8 x (2.5) 2 x √15
Q 1 = 577.8 gpm
Both outlets are 2 ½ in., with the same outlet coefficient. Therefore, Q 1
=Q2
The total flow rate is then: Q 1 + Q 2 = Q total
Q total = 577.85 gpm + 577.85 gpm = 1155.70 gpm, round up to 1156
gpm
If a cross main in a ________ pipe sprinkler system has three branch
lines per bay, one intermediate hanger shall be permitted to be omitted,
if a branch line hanger is installed on the starter peice. - ANSWER-Steel.

Reference NFPA 13 2016, Section 9.2.4.3.
NFPA 13 specifies the depth of cover fro underground pipe of a
minimum of 2 1/2 ft, 3 ft. under driveways and 4 ft. under railroads
tracks. However, it must be at least 1ft. below the frost line. If the frost
line is 2 1/2 ft, what is the minimum depth of cover under a driveway? -
ANSWER-3 ½ ft.
Reference NFPA 13 2016, Section 10.4. If you are laying pipes under
driveways, you must go down a minimum of 3 ft. However, you must be
at least 1 ft. below the frost line. In this case that is 3 ½ ft.
Ordinary Hazard is a term that specifies: - ANSWER-An occupancy
classification, More combustibility than light hazard, and A system area
limitation of 52,000 ft 2 .
Reference NFPA 13 2016, Sections 5.3 and 8.2.1.
What type of temperature is required for a sprinkler installed 2ft above a
heating duct? - ANSWER-Intermediate.
Reference NFPA 13 2016, Table 8.3.2.5(a).
