blueprint is shown as half of its actual size
\A computerized maintenance management system (CMMS) is a type of .... - ANS - tool
\What problems may occur when a person works in a very hot area for a prolonged period of
time? - ANS - Heat stroke, Cramps, Exhaustion
\What is the purpose of a confined space safety permit? - ANS - It ensures the use of safety
precautions and use of standard safety procedures when working in a confined space
\Why must preventative maintenance tasks be documented? - ANS - Records are needed to
show the type and frequency of maintenance of operating units and to evaluate the

\True or False : When accepting a work order, the need for speedy completion is an integral
aspect of your performance as a Maintainenance Technologist - ANS - FALSE : It does not
matter how long it takes to complete a work order, the most important and integral aspect of

, \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? - ANS - 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? -
ANS - 1680 lbs/ft
48' * 35lbs = 1680
\What is the definition of Arc Welding? - ANS - 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? - ANS - 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? - ANS - An outward force on a mass when it is rotated
\How does a positive displacement pump work? - ANS - 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? - ANS - 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? - ANS - Epoxy coatings
\What is a wet well? - ANS - A tank, a portion of a water system that temporarily stores water
before it is pumped elsewhere
\What does "galvanized" mean? - ANS - Coated with a protective layer of zinc
\What does PVC stand for? - ANS - Polyvinyl chloride, a type of plastic used for pipes
\What is the formula for horsepower? - ANS - hp = Fd/t
Force (in lbs) multiplied by distance (in feet) divided by time (in minutes)
\What are volts? - ANS - A unit of electric potential
\What is the equation for volts? - ANS - Volts = watts/amps
\What are amps? - ANS - A unit of electric current
\How do you calculate amps? - ANS - Amps = watts / volts
\What are watts? - ANS - A watt is a unit of power
\How do you calculate watts? - ANS - Watts = amps * volts
\What are ohms? - ANS - A measurement of resistance between two points
\How do you calculate ohms? - ANS - Ohms (R) = volts / amps
\What does pneumatic mean? - ANS - Containing or operated by gas or air under pressure
\The specific gravities of gasoline and other volatile solvents are typically __________________
than water - ANS - less than, meaning they will float
\How many gallons are in 1 ft^3? - ANS - 7.48
\If a gallon of gasoline weighs 7 lbs, what would be the weight of a 350-gallon tank full of
gasoline? - ANS - 350 gal * 7lbs(per 1gal) = 2,450 lbs
