TPC 275 QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTION
another name for the ratio of the density of a liquid to the density of water is
Answer - relative density
the resistance of a fluid to movement or flow is its Answer - viscosity
in what kind of flow do frictional resistance and eddy currents occur Answer -
turbulent
the kind of fluid flow in a pipe is determined by the size of the pipe, viscosity
and relative density of the fluid, and the Answer - fluid viscosity
as a fluid flows through a widening pipe, its Answer - viscosity decreases
the circulation of an enclosed fluid caused by uneven temperatures is called
Answer - convection
a pump that draws liquid from a level is said to operate with a Answer -
suction lift
every inch of vacuum in a pumping system adds how many feet to the suction
lift Answer - 1.0
, the distance that a piped fluid flows in a certain amount of time is its Answer -
flow velocity
which of the following helps liquid flow in a pipe Answer - head pressure
as flow rate of a fluid in a completely filled pipe changes, the internal pressure
and the________ change Answer - velocity
measurements that sense flow rate from changes in fluid velocity, depth, or
pressure are referred to as Answer - indirect
head, which causes fluid to flow in a pipe, is another name for Answer - static
pressure
the basic pilot in a(n)______ measuring device Answer - one port
the speed of fluid through a venturi tube is fastest Answer - at the throat
static head is equivalent to a flowing fluid's Answer - potential energy
the measurement device used more than any other to restrict fluid flow is the
Answer - orifice plate
which kind of orifice should you use for pipes smaller than 1 in. in diameter
Answer - beveled edge
if there is a danger of hot liquid flashing into vapor, the orifice should have a(n)
Answer - vent hole at the top of the plate
