Reference NFPA 13 2016, Section 23.1.3(35).
NFPA 13 defines the information which should be included in the working plans to be submitted
to the AHJ for approval. These include which of the following: - answer-:Location, Occupancy
Classification, Location of concealed spaces, Area protected by each sprinkler, Number of
sprinklers.
Reference NFPA 13 2016, Section 23.1.3.
Who must sign the Owner's Certificate? - answer-:The owner or the owner's representative.
Reference NFPA 13 2016, Figure A.23.1(b). The Owner's Certificate declares the intended use of
the occupancy to be protected.

100 gpm is flowing through 100' of 1 1/4in Schedule 40 pipe. How many feet of 1 1/2in pipe will
produce the same friction loss? - answer-:Step #1: Assume this is Schedule 40 pipe, C = 120. Use
the Hazen-Williams formula to calculate the friction loss for the 1 ¼ in. pipe and the 1 ½ in. pipe.
For 1 ¼ in. pipe (ID = 1.38):
P friction loss = 4.52 x Q 1.85
c 1.85 x d 4.87
P friction loss = 4.52 x 100 1.85
120 1.85 x 1.38 4.87
P friction loss = 0.672 psi/ft
