Flow Measurements Questions and answer

 Q & A For Flow Measurements

1.Convert the flow of 3 Cu ft/min into Cu meters/hour.

Solution

1 Cu ft/min = 1.699 Cu meters/hour

So, 3 Cu ft/min = 3 x 1.699 Cu meters/hour

 = 5.097 Cu meters/hour 

2 .Convert the flow of 9 Imp. Gallons into Barrels(oil).

Solution

1 Imp. Gallons = 0.0286 Barrels

So, 9 Imp. Gallons = 9 x 0.0286 Barrels

 = 0.2574 Barrels

3.Convert the flow of 2 lb./sec into gm/min.

Solution

1lb./sec = 27220 gm/min

So, 2 lb./sec = 2 x 27220 gm/min

 = 54440 gm/min

4. Convert the flow of 10 meter/sec into cm/sec. 

Solution

1 meter/sec = 100 cm/sec

So, 10 meter/sec = 10 x 100 cm/sec

 = 1000 cm/sec 

5. Convert the flow of 18 ft/sec into meter/min.

Solution

1 ft/sec = 18.29 meter/min

So, 18 ft/sec = 18 x 18.29 meter/min

 = 329.22 meter/min

6. Convert the flow of 57 ft/min into meter/sec.

Solution

 1 ft/min = 0.005080 meter/sec

 So, 57 ft/sec =57 x 0.005080 meter/sec

 =0.28956 meter/sec

7. Convert the flow of 10 Imp. Gallons into Barrels.

Solution

 1 Imp. Gallon = 0.0286 Barrels

 So, 10 Imp. Gallons = 10 x 0.0286 Barrels

 = 0.286 Barrels.

8. Convert the flow of 100 meter/sec into meter/min.

Solution

 1 meter/sec = 60 meter/min

 So, 100 meter/sec = 100 x 60 meter/min

 = 6000 meter/min

9. Inferential method of measurement measures some related property and 

then converts to flow rates. True/False?

True.

10. Oval gear type flow meter is a type of inferential flow meter. True/False?

False.

11. In case of orifice plate flow metering system, the flow rate is proportional to the square root of differential pressure. True / False?

True.

12. In PDO, flange tapping is the most commonly used type of orifice tapping. True/False?

True.

13. On the square root scale, the distance between each small division is decreasing as the readings go higher. True / False?

False.

14. Flow Nozzle is suitable for process applications involving slurries. True/False?

True.

15. The frequency output of a turbine flow meter varies linearly with the volumetric flow rate. True / False?

True.

16. Ultrasonic devices use high frequency sound waves or vibrations to detect the flow in a pipe line. True/False?

True.

17. Lobed-impeller flow meter is mainly used for liquids. True / False?

False.

18. The Coriolis flow meters can be used for both clean & viscous fluids.True/False?

True.

19. Paddle type flow switch can be mounted in vertical pipeline. True / False? 

False.

20. Meter prover loop is used to calibrate the flow meter approved for custody transfer of crude oil for accuracy at regular intervals. True/False?

True.

21. Density of gas is more affected than liquids by varying pressure and temperature. True / False?

True.

22. Viscosity is the property that determines how freely fluid flows. True/False?

True.

23. What is density?

Solution

Density is defined as the mass per unit volume.

 ρ = m/v

Where ρ = Density

 m = Mass.

 v = Volume

24. Turbulent flow is the most common type of flow pattern encountered in oil industry. True/False?

True.
