MATHEMATICS FOR PLUMBERS AND
PIPEFITTERS CERTIFICATION EVALUATION TEST
COMPLETE QUESTIONS AND CORRECT
ANSWERS
◉ Allowance for Threaded Fittings.
Answer: Additional length added to pipe measurements to account
for the space taken up by threaded connections.
◉ Copper Tubing.
Answer: A type of piping made from copper, known for its durability
and resistance to corrosion.
◉ Plastic Pipe.
Answer: A lightweight, flexible piping material made from various
types of plastic, often used in residential plumbing.
◉ Welded Steel Pipe.
Answer: A type of pipe made from steel that is joined by welding,
providing strength and durability.
◉ Angles in Plumbing.
,Answer: Specific measurements used to determine the direction of
pipes and fittings in plumbing systems.
◉ Offset.
Answer: A change in direction of a pipe, typically measured in
degrees, to navigate around obstacles.
◉ Diagonal.
Answer: A line that connects two non-adjacent corners of a
geometric shape, often used in layout calculations.
◉ Grade.
Answer: The slope or incline of a pipe, typically expressed as a
percentage, affecting drainage and flow.
◉ Elevation.
Answer: The height of a point in relation to a reference level,
important for ensuring proper drainage.
◉ Water Pressure.
Answer: The force exerted by water in a system, crucial for
determining flow rates and pipe sizing.
,◉ Heat Loss.
Answer: The amount of heat energy lost from a space, often
calculated to size heating systems appropriately.
◉ Radiator Size.
Answer: The dimensions and capacity of a radiator, determined by
the heat loss of the space it serves.
◉ Pipe Sizing.
Answer: The process of determining the appropriate diameter of
pipes based on flow requirements and pressure.
◉ Miter Cuts.
Answer: Angled cuts made on pipes to allow for proper fitting and
alignment in plumbing installations.
◉ Powers.
Answer: The result of raising a number to a certain exponent,
indicating how many times to multiply the number by itself.
◉ Metric Measure.
Answer: A system of measurement based on the meter, liter, and
gram, used widely around the world.
, ◉ Decimal Inch.
Answer: A measurement system that uses decimal fractions of an
inch instead of fractions.
◉ Elbow Fitting.
Answer: A plumbing fitting used to change the direction of a pipe,
typically at a 90° or 45° angle.
◉ Wye Fitting.
Answer: A plumbing fitting that allows three pipes to connect at a
junction, resembling the letter 'Y'.
◉ Tee Fitting.
Answer: A plumbing fitting that allows for the connection of three
pipes, forming a 'T' shape.
◉ Pipe Diameter.
Answer: The measurement across the circular cross-section of a
pipe, which determines the flow capacity.
◉ Fitting Allowance.
