INSTRUMENTATION TEST I- FLOW
MEASUREMENT EXAM WITH
CORRECT QUESTIONS AND ANSWERS
2025
1. Flow rate - CORRECT-ANSWERSThe quantity of fluid passing a point at
a particular moment.
2. Total flow - CORRECT-ANSWERSThe quantity of fluid that passes a point
during a specific time interval.
3. Density - CORRECT-ANSWERSMass per unit volume.
4. Specific gravity - CORRECT-ANSWERSThe ratio of the density of a fluid
to the density of a reference fluid.
5. Absolute viscosity: - CORRECT-ANSWERSThe resistance to flow of a fluid
and has units of centipoise (cP).
6. Kinematic viscosity - CORRECT-ANSWERSThe ratio of absolute viscosity
to fluid density and has units of centistokes (cS).
7. Reynold's number: - CORRECT-ANSWERSThe ratio between the inertial
forces moving a fluid and viscous forces resisting that movement.
8. Laminar flow - CORRECT-ANSWERSSmooth fluid flow that has a flow
profile that is parabolic in shape with no mixing between the streamlines.
9. Turbulent flow - CORRECT-ANSWERSFluid flow in which the flow profile
is a flattened parabola, the streamlines are not present, and the fluid is
freely intermixing.
, 10. Incompressible fluid - CORRECT-ANSWERSA fluid where there is
very little change in volume when subjected to a change in pressure.
11. Compressible fluid - CORRECT-ANSWERSA fluid where the volume
and density change when subjected to a change in pressure.
12. Standard condition - CORRECT-ANSWERSAn accepted set of
temperature and pressure conditions used as a basis for measurement.
13. Flowing condition: - CORRECT-ANSWERSThe pressure and
temperature of the gas or vapor at the point of measurement.
14. Boyle's law - CORRECT-ANSWERSA gas law that states that the
absolute pressure of a given quantity of gas varies inversely with its
volume provided the temperature remains constant.
15. Charles' law - CORRECT-ANSWERSA gas law that states that the
volume of a given quantity of gas varies directly with its absolute
temperature provided the pressure remains constant.
16. Gay-Lussac's law - CORRECT-ANSWERSA gas law that states that
the absolute pressure of a given quantity of a gas varies directly with its
absolute temperature provided the volume remains constant.
17. Primary flow element - CORRECT-ANSWERSA pipeline restriction
that causes a pressure drop used to measure flow.
18. Orifice plate - CORRECT-ANSWERSA primary flow element
consisting of a thin circular metal plate with a sharp-edged round hole in
it and a tab that protrudes from the flanges.
