A deep vacuum is an evacuation method in which a technician uses a vacuum
pump (or the systems compressor) to pull a vacuum until no moisture or other
vapor remains in the system. If the compressor is used for this procedure, but
CANNOT produce a deep vacuum, which of the following would be the problem?

D- leaky exhaust valve C- leaky suction valve
Use a duct slide rule to determine required round steel duct size for a sheet metal
duct system showing a pressure drop of 0.25 IWC, delivers 1,000CFM, has a total
effective length of 263 feet, and a friction rate of 0.095 IWC/100.

C- 16 inch diameter
D- 14 inch diameter D- 14 inch diameter (ACCA Ductulator (duct slide rule)
align 0.095 on galvanized metal duct /w 1000CFM = 14" round duct. 14 inch
diameter)
What is the minimum required outdoor ventilation rate for a residence with three
bedrooms, the bathrooms, one kitchen, and a 133 square foot one-car garage?
(Assume continuous exhaust for kitchen and bathrooms.)
A- 115 CFM
B- 175 CFM
C- 225 CFM
D- 295 CFM C- 225CFM (IMC - TABLE 403.3.1.1
The Manual J specific heat formula used for changing the temperature is
CFM=BTUh/(1.08 x Change Temperature). Therefore, what would be the required
heat input in BTUs to raise air quantity of 120CFM from the cold temperature of
30 deg F to a warm temperature of 80 deg F (without and altitude correction
factor)?
A- 8573 BTUh
B- 7824 BTUh
C- 6660 BTUh
D- 5231 BTUh C- 6660 BTUh (BTUh= 120CFM x 50deg F x 1.08 = 6480BTUh)
According to OSHA, upper and lower guards shall be equipped on...
A- grinding machines
, B- portable, power-driven circular saws

D- 30 A- 24 (IMC - TABLE 603.4 lists the required aluminum thickness of 0.018
inches minimum, for a round duct less than 12 inches diameter. A standard
sheet metal thickness gauge table will list the thickness of 24 gauge aluminum
as 0.0201 inches, and the thickness of 26 gauge aluminum as 0.0159 inches (too
thin). Correct multiple choice answer is 24 gauge aluminum duct (0.0201
inches).
