saw
/.A scale on a blueprint indicates 1" = 2". What does this scale mean? - Answer-✅Each
line on the blueprint is shown as half of its actual size
/.A computerized maintenance management system (CMMS) is a type of .... - Answer-
✅tool
/.What problems may occur when a person works in a very hot area for a prolonged
period of time? - Answer-✅Heat stroke, Cramps, Exhaustion
/.What is the purpose of a confined space safety permit? - Answer-✅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? - Answer-✅Records are
needed to show the type and frequency of maintenance of operating units and to
evaluate the effectiveness of maintenance programs
/.True or False : When accepting a work order, the need for speedy completion is an
integral aspect of your performance as a Maintainenance Technologist - Answer-
✅FALSE : It does not matter how long it takes to complete a work order, the most
important and integral aspect of your performance when completing a work order is

/.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? -
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? - Answer-✅1680 lbs/ft
48' * 35lbs = 1680
, /.What is the definition of Arc Welding? - 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? - 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? - Answer-✅An outward force on a mass when it is rotated
/.How does a positive displacement pump work? - 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? - 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? - Answer-✅Epoxy
coatings
/.What is a wet well? - Answer-✅A tank, a portion of a water system that temporarily
stores water before it is pumped elsewhere
/.What does "galvanized" mean? - Answer-✅Coated with a protective layer of zinc
/.What does PVC stand for? - Answer-✅Polyvinyl chloride, a type of plastic used for
pipes
/.What is the formula for horsepower? - Answer-✅hp = Fd/t
Force (in lbs) multiplied by distance (in feet) divided by time (in minutes)
/.What are volts? - Answer-✅A unit of electric potential
/.What is the equation for volts? - Answer-✅Volts = watts/amps
/.What are amps? - Answer-✅A unit of electric current
/.How do you calculate amps? - Answer-✅Amps = watts / volts
/.What are watts? - Answer-✅A watt is a unit of power
