For preliminary sizing of an all air, or air-water HVAC system, what percentage of the
floor area should be allotted? - answer3% to 10%.
Why should mechanical equipment (HVAC) rooms be located in the basement? -
answerFor smoke control in a fire. (Smoke rises and will move away from the
equipment).
In an HVAC system, frictional resistance between air and duct walls is called _______,
and is measured in _______. - answerstatic head, and is measured in inches of water.
Longer ductwork = more _______. - answerfriction
How is friction between air and duct walls overcome? - answerBy enlarging ducts, or by
increasing the size of fans.
,For initial sizing of both supply and return ducts, allow a cross sectional area of
_______ sq. ft. to _______ sq. ft. for every 10,000 square. ft. of floor space. - answer10
sq. ft to 20 sq. ft.
What does an hvac mixing box do? - answerControls air flow from the main supply line,
by adjusting quantity and temperature, while reducing velocity and noise.
What does VAV stand for? - answerVariable Air Volume.
What does a VAV box do? - answerReceives air at a constant temperature, then varies
the air flow rate into the room to adjust the temperature.
A plenum is... - answer...the space between a suspended ceiling and the structural floor
above.
How much of the plenum space does a suspended ceiling usually take up? - answer2
inches
Thermostats are normally located _______ inches above the floor. - answer48
When may a thermostat be located 44 inches above the floor. - answerFor accessibility,
when an obstruction extends 20 in. to 25 in. from the wall.
Where are supply registers best placed? - answerNear areas of heat loss or gain, such
as windows.
Where are return air grilles best placed? - answerFar from the supply registers.
How much pressure is required to raise water 1 foot. - answer0.433 psi.
List the three grades of copper pipe from thickest to thinnest. - answerK, L, and M.
What type of water pipe material is manufactured in continuous lengths on spools, so it
can be cut to length, eliminating the need for fittings. - answerPEX (cross-linked
polyethylene)
Why is PEX more environmentally friendly than copper? - answerBecause of copper's
environmentally intensive extraction and manufacturing processes.
How is PEX pipe connected? - answerBy compression and crimping with a special tool.
In regards to plumbing, what is demand load? - answerThe flow rate that would be
needed if every fixture in the system were in use at the same time.
How is demand load calculated? - answerBy adding the load values (found on a chart)
of all fixtures in the system.
, What are the two types of bolted connections? - answer1. Bearing Type
2. Slip Critical
Which blocks sound better, a wall with a high STC or a wall with a low STC? - answerA
high STC
What is a bearing type connection? - answerThe load is actually resting (at least
partially) on the bolt, because the bolt holes are larger than the bolt and the pieces of
steel being connected have shifted until they are bearing against the bolt.
What is a slip-critical connection? - answerA connection where the entire load is carried
by the friction of the two pieces which have been bolted together, and the bolt carries no
loat at all.
What are the codes used for the conditions of use of a bolted connection? - answerSC:
slip critical
N: bearing connection
X: bearing connection with threads EXCLUDED from the shear plane.
S: single shear
D: double shear

ends, tops and sides. - answer1/2 inch
Wood used for construction of permanent structures, located less than _______ inches
from the ground must be treated or naturally decay resistant. - answer6 inches
Air entrainment concrete admixture increases... - answerfreeze/thaw durability.
Typically for every one percent of entrained air, compressive strength of concrete will be
reduced by about _____ percent. - answerfive percent.
Know how to find linear thermal expansion. - answerTo do this: multiply the provided
coefficient by the original length by the change in temperature. Then add or subtract
