New Exam Questions With Answers
What is 1 horsepower equal to in BTU/minute? - correct -answer-42.45
What is 1 MGD in cubic feet (ft^3) per second? - correct -answer-1.55
ft^3/sec
What is 1 BTU equal to in foot-pounds? - correct -answer-778 foot-pounds
What is 1 watt equal to in BTU/hour? - correct -answer-3,412 BTU/hour
1 Thermal Unit is equal to ______________ BTU - correct -answer-
100,000 BTU
Which welding process is most commonly used for small pipe maintenance
welding? - correct -answer-OxyAcetylene gas welding
What types of jobs would you need Shielded metal-arc welding for? -
correct -answer-Constructing pipelines, tanks, industrial construction,
structures
What types of jobs do you need Gas metal-arc welding for? - correct -
answer-Deep groove welding, automotive repair, manufacturing heavy
equipment
,What types of jobs do you use Gas tungsten-arc welding for? - correct -
answer-Thin sections of stainless steel and other precise jobs dealing with
dissimilar metals
What is wet stacking and how can it be prevented? - correct -answer-It is
unburned fuel collecting in the exhaust due to light or no load conditions.
To check flywheel face turnout, where should the dial indicator be
positioned? - correct -answer-The base on the well housing and the
pointer on the flywheel face.
What issues arise with excessive flywheel face turnout? - correct -answer-
Excessive runout can lead to uneven pressure distribution on the clutch
disc, affecting its performance. Runout causes additional friction and drag,
leading to clutch slippage, poor release, and difficulty shifting gears.
If a 38-tooth gear running at 360 rpm is driving another gear at 144 rpm,
what is the number of teeth on the driven gear? - correct -answer-95
Solution: driver Gear x Driver RPM=Driven Gear x Driven RPM38 x 360 =
N x 14413,680 = 144N13, = 144N / 14495 = N(95 Tooth Gear
What equation would you use to figure out the rpm of a Gear Driver? -
correct -answer-Gear Driver (number of teeth) x Driver RPM = Driven
Gear (number of teeth) x Driven RPM
Does a sealed ball bearing need to be lubricated? - correct -answer-It
does not need to be lubricated under normal use
A DAFT is an acronym meaning......... - correct -answer-Dissolved Air
Flotation Thickener
, What is the governing agency that permits odor control systems? - correct
-answer-AQMD - Air Quality Management District
At what pressure rating should you use a blower instead of a fan? - correct
-answer-7 psi
What is the difference between a blower and a fan? - correct -answer-The
main difference between a blower and a fan is that a fan is an electrical
device that moves air, whereas a blower is a mechanical device that
consists of a fan and channels the air from the fan to a specific location or
point. Fans circulate air around an entire room or a large area, while
blowers generate a concentrated, high-pressure airflow aimed at specific
directions or through confined spaces. Another difference is that fans
primarily focus on producing high-volume airflow at low pressure, while
blowers are designed to force air through targeted areas
What is a globe valve used for? - correct -answer-Regulate fluid flow, can
be throttled up of down or shut off flow completely
What type of valve is unsuitable for high-pressure flow? - correct -answer-
A needle valve
What is a gate valve used for? - correct -answer-Gate valves are among
the most common sorts of valves and taps you will find in most pipeline
applications for stopping and starting fluid flow
What is a needle valve used for? - correct -answer-A needle valve is a
type of valve that uses a tapered needle to control the flow of fluid. It is
often used in applications where precise control of the flow rate is required,
such as in laboratory and industrial settings. The unique feature of the
valve is the structure of a small plunger with the shape of a needle. The
plunger features a small handle to operate in the easy and precise
operation of the valve.
