What does one cubic foot of water weigh? ---------CORRECT ANSWER-----------------
62.5 lbs
What does One cubic foot of water contain in inches? ---------CORRECT ANSWER---
--------------1.728 cubic inches
What does One cubic foot of water contain in gallons? ---------CORRECT ANSWER--
---------------7.5 gallons
What does One gallon of water weigh? ---------CORRECT ANSWER-----------------8.35
lbs
What does One gallon of water contain in inches? ---------CORRECT ANSWER--------
---------231 cubic inches
What is One foot of water exert as a back pressure? ---------CORRECT ANSWER-----
------------.434 psi
,How high will One psi elevate water? ---------CORRECT ANSWER-----------------2.304
feet
What is atmospheric pressure at sea level? ---------CORRECT ANSWER-----------------
14.7 psi
What is the maximum lift for drafting? (Theoretically) ---------CORRECT ANSWER---
--------------34 feet
How high does One inch (1") mercury (inches in vacuum) lift? ---------CORRECT
ANSWER-----------------1.13 feet of lift
What is the recommended minimum psi that should be maintained on the
compound gauge when taking water from a hydrant? ---------CORRECT ANSWER---
--------------10 psi
What is Static pressure? ---------CORRECT ANSWER-----------------Stored or potential
energy that is available to force water through pipes and fittings, fire hose, and
adapters.
,Residual Pressure ---------CORRECT ANSWER-----------------That part of the total
pressure that is not used to overcome friction or gravity while forcing water
through fire hose, pipe, fittings, and adapters.
How to calculate psi loss for each additional line off hydrant and know how many
lines can be taken off hydrant? ---------CORRECT ANSWER-----------------Take Static
pressure and subtracting residual pressure which gets you your drop. Take your
drop and multiply it by (2)² for second line, (3)² for third line, (4)² for forth line,
(5)² for fifth line. so long as after you multiply drop and the multiplayer for the
number line and still have 10 psi left based off static pressure you can have that
many lines if you have less than 10 psi you can not operate that number of lines.
Examples of how to calculate psi loss for each additional line off hydrant ---------
CORRECT ANSWER-----------------Example: Static pressure: 65 psi Residual pressure
: 60 psi
Drop: 5 psi
2nd line: 2²=4: 4x5= 20
3rd line: 3²=9: 9x5= 45
4th line: 4²=16: 16x5= 80 This line can't be done because it is over 65 psi
What are all the steps in Certification Test (pre-service tests)? ---------CORRECT
ANSWER-----------------1. 2 Hour: 100% @ 150 psi
2. 1/2 hour: 70% @ 200 psi
3. 1/2 hour: 50% @ 250 psi
, 4. 10 minutes: 100% @ 165 psi (overload or spurt test)
What is a Spurt or Overload test? ---------CORRECT ANSWER-----------------100% @
165 psi (done in certification test for 10 minutes)
What are all the steps in a Service Test? ---------CORRECT ANSWER-----------------1.
20 minutes: 100% @ 150 psi
2. 10 minutes: 70 % @ 200 psi
3. 10 minutes: 50% @ 250 psi
Optional: 100% @ 165 psi (overload or spurt test)
What are Pump Tests? ---------CORRECT ANSWER-----------------100% capacity @
150 psi net pump pressure
70% capacity @ 200 psi net pump pressure
50% capacity @ 250 psi net pump pressure
What is Net Engine/Pump Pressure (NEP)? ---------CORRECT ANSWER-----------------
Net Pump Pressure (NEP) is the measurement of the total work performed by the
pump:
a. To lift water into the pump (drafting)
b. To discharge water from the pump
NEP= Suction Side Work(drafting) + Discharge Side Work
