A scale on a blueprint indicates 1" = 2". What does this scale mean? - correct answer Each line
on the blueprint is shown as half of its actual size
,A computerized maintenance management system (CMMS) is a type of .... - correct answer tool
What problems may occur when a person works in a very hot area for a prolonged period of
time? - correct answer Heat stroke, Cramps, Exhaustion

safety precautions and use of standard safety procedures when working in a confined space
Why must preventative maintenance tasks be documented? - correct answer Records are
needed to show the type and frequency of maintenance of operating units and to evaluate the

There is an 18" wide red stripe painted on the ground around a tank. The tank is 25' high and
150' in diameter. What is the perimeter on the outer edge of the stripe? - correct answer
475.71 ft
18" = 1.5'
Perimeter = Diameter * pi = (150' + 1.5') * 3.14 = 475.71
A 12" diameter pipe, 48' long, weighs 35lbs per linear ft. What is the weight of the total load? -
correct answer 1680 lbs/ft
48' * 35lbs = 1680
What is the definition of Arc Welding? - correct answer Arc Welding is a welding process that is
used to join metal to metal by using electricity to create enough heat to melt metal, and the
melted metals, when cool, result in a binding of the metals
How does a centrifugal pump work? - correct answer Moves fluid by means of rotational
energy from rotor drives/impellers. Fluid enters the rapidly rotating impeller along its axis and
is cast out by centrifugal force along its circumference through the impeller's vein tips
What is centrifugal force? - correct answer An outward force on a mass when it is rotated
How does a positive displacement pump work? - correct answer Pump moves fluid by
repeatedly enclosing a fixed volume of fluid, with the aid of seals or valves, and moving it
mechanically (with a piston or a plunger) through a system
How does a vacuum pump work? - correct answer Vacuum pumps have an inlet and and outlet
with a nozzle in between - the nozzle restricts flow of fluids, thereby increasing fluid's velocity
, and decreases the fluids pressure. A vacuum is created by the lack of pressure which pulls the
fluid into the nozzle and forces it out the other side
What types of coatings are usually used on the inside of wet wells? - correct answer Epoxy
coatings
What is a wet well? - correct answer A tank, a portion of a water system that temporarily stores
water before it is pumped elsewhere
What does "galvanized" mean? - correct answer Coated with a protective layer of zinc
What does PVC stand for? - correct answer Polyvinyl chloride, a type of plastic used for pipes
What is the formula for horsepower? - correct answer hp = Fd/t
Force (in lbs) multiplied by distance (in feet) divided by time (in minutes)
What are volts? - correct answer A unit of electric potential
What is the equation for volts? - correct answer Volts = watts/amps
What are amps? - correct answer A unit of electric current
How do you calculate amps? - correct answer Amps = watts / volts
What are watts? - correct answer A watt is a unit of power
How do you calculate watts? - correct answer Watts = amps * volts
What are ohms? - correct answer A measurement of resistance between two points
How do you calculate ohms? - correct answer Ohms (R) = volts / amps
What does pneumatic mean? - correct answer Containing or operated by gas or air under
pressure
The specific gravities of gasoline and other volatile solvents are typically __________________
than water - correct answer less than, meaning they will float
How many gallons are in 1 ft^3? - correct answer 7.48
If a gallon of gasoline weighs 7 lbs, what would be the weight of a 350-gallon tank full of
gasoline? - correct answer 350 gal * 7lbs(per 1gal) = 2,450 lbs
What is 500 gpm in MGD? - correct answer 500gal/1 min * 1440 min = 720,000 gal per day /
1,000,000 = 0.72 MGD
