How does a centrifugal pump work?—Ans: Moves fluid by means
Guru01 - Stuvia
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
