MATHEMATICS FOR PLUMBERS AND
PIPEFITTERS EXAM PREP QUESTIONS AND
ANSWERS FULLY VERIFIED
◉ Hydraulics.
Answer: The branch of science concerned with the mechanics of
fluids in motion and at rest.
◉ Pressure.
Answer: The force exerted by a fluid per unit area, commonly
measured in pounds per square inch (psi).
◉ Flow Rate.
Answer: The volume of fluid that passes through a given surface per
unit of time, often expressed in gallons per minute (GPM).
◉ Welding.
Answer: A fabrication process that joins materials, typically metals
or thermoplastics, by causing coalescence.
◉ Blueprint.
,Answer: A detailed architectural or engineering drawing that
outlines the specifications for construction projects.
◉ Fittings.
Answer: Components used to connect straight sections of pipe or
tubing, adapt to different sizes or shapes, and regulate fluid flow.
◉ Valves.
Answer: Devices that control the flow of liquids or gases in a piping
system by opening, closing, or partially obstructing passageways.
◉ Thermodynamics.
Answer: The branch of physics that deals with heat and temperature
and their relation to energy and work.
◉ Soldering.
Answer: A process of joining two or more electronic parts together
by melting solder around the connection.
◉ Ventilation.
Answer: The process of supplying fresh air and removing stale air
from a space to maintain air quality.
,◉ Drainage.
Answer: The system of removing excess water or liquid waste from a
particular area.
◉ Measurement.
Answer: The process of determining the size, length, or amount of
something, often using specific tools like tape measures or calipers.
◉ Safety Precautions.
Answer: Measures taken to ensure the safety of individuals while
performing tasks, particularly in hazardous environments.
◉ Code Compliance.
Answer: Adherence to local, state, and federal regulations and
standards governing plumbing and pipefitting practices.
◉ Basic Rules for Mathematics.
Answer: Fundamental principles that govern the operations of
addition, subtraction, multiplication, and division.
◉ Formulas.
Answer: Mathematical expressions that represent relationships
between different quantities, often used to solve problems.
, ◉ Solving Formulas/Equations.
Answer: The process of finding the value of variables in
mathematical expressions that are set equal to each other.
◉ Square Root.
Answer: A value that, when multiplied by itself, gives the original
number; often used in calculations involving area.
◉ Angle Measure.
Answer: A way to quantify the rotation between two rays that share
a common endpoint, typically measured in degrees.
◉ Conversion of Length Measure.
Answer: The process of changing a measurement from one unit to
another, such as inches to feet.
◉ Standard Weight Pipe.
Answer: A type of pipe that has a specific weight per unit length,
commonly used in plumbing.
◉ Allowance for Threaded Fittings.
