When conducting a hydrostatic flow test for a new fire sprinkler
system, the test pressure should be _______ psi for ________ hours. -
<<,Answers>>>200, 2.
Reference NFPA 13 2016, Section 25.2.1.1.
Supplementary conditions of a contract contain which of the
following: - <<,Answers>>>Delay agreements, Time and pay
schedules, and Addendums. Reference course content.
Determine the max allowable shutoff pressure for a fire pump with a
rated cpacity of 750 gpm and a rated head of 60 ft. -
<<,Answers>>>36 psi.
1.4 x 60 ft = 84 ft,
Head = P psi/0.433,
P = Head x 0.433, P = 84 x 0.433 = 36.37 psi.
,This complex phenomenon specific to pumps or other hydraulic
equipment is the result of suction pressure falling below vapor
pressure corresponding to the water temperature: -
<<,Answers>>>Cavitation

In a manufacturing plant classified as Ordinary Hazard Group 2, the
sprinkler system is provided with one inside hose station. Per NFPA
13 2016, Table 11.2.3.1.2. what is the minimum inside hose demand?
- <<,Answers>>>50 gpm
A water flow test was conducted using 2 hydrants. Both 2 1/2" outlets
were used on hydrant #1 while one outlet was used on hydrant #2.
The pitot reading at each hydrant was 12 psi. If the discharge
coefficient is 0.7, what is the total water flow (gpm) during this test? -
<<,Answers>>>The correct answer is 1356 gpm .
Solution #14:
Q = 29.84 cd 2 √P
, Q 1 = 29.84 x 0.7 x (2.5) 2 x √12 = 452.09 gpm
Q 2 = 29.84 x 0.7 x (2.5) 2 x √12 = 452.09 gpm
Q 3 = 29.84 x 0.7 x (2.5) 2 x √12 = 452.09 gpm
Q total = Q 1 + Q 2 + Q 3
Q total = 452.99 gpm + 452.99 gpm + 452.99 gpm = 1356.27 gpm
Round down to 1356 gpm
In a water flow test using two hydrants, _________ pressure
is the pressure at the hydrant where the water is not flowing. -
