No answer description available for this question.

Prasanna said: (Sep 19, 2013)  
Pitot tube is used for to find out the velocity of the flow pipes or soil etc.

Amit Dauwar said: (Jan 31, 2014)  
Pitot tube is used to measure velocity of Flow in pipes.

Khan said: (Mar 22, 2014)  
Velocity of the flow at the required point in a pipe.

Navid Ur Rehman said: (Apr 22, 2014)  
Is a pressure measurement instrument used to measure fluid flow velocity?

Naresh said: (Jul 15, 2014)  
Definitely pitot tube and venturi meter are used to find the velocity of fluid in a pipe i.e. v=sqrt(2g(h1-h2)).

Jay Mishra said: (Aug 29, 2014)  
Pilot tube used to find out velocity of flow by pressure.

Deepak said: (Oct 7, 2014)  
Pitot tube measure the velocity of fluid flow in pipe and channel also.

Sujan said: (Mar 24, 2015)  
Pitot tube is used to measure the velocity in pipe or channels.

Czana Bt said: (May 9, 2015)  
It is used to measure the velocity of flow.

Gandhi Battu said: (Jun 28, 2015)  
Pitot tube is provided to find the velocity at required point. And it also used for increase (or) decrease of velocity.

Chozhapandiyan said: (Nov 20, 2015)  
Pitot tube is measure the velocity of flow.

Sach said: (Mar 3, 2016)  
Pitot tube is used to measure the velocity of flow.

Anil Gogineni said: (Jun 20, 2016)  
Pitot tube is used to measure the fluid flow velocity.

Hailegebrailtegegn said: (Jul 8, 2016)  
Pitot tube is used to measure the velocity in the pipe and canal.

Jay said: (Aug 25, 2016)  
Pitot-static tube is used to measure the fluid flow velocity. Pitot tube is used to measure pressure. So the answer is wrong.

Sai said: (Sep 29, 2016)  
Pitot tube is used to measure the velocity of the fluid at that point only.

Krishna said: (Oct 20, 2016)  
It is not a flow velocity.

Velocity at a given point or pressure difference can be measured by pitot tube.

Vivek Singh said: (Oct 23, 2016)  
It is used to measure the velocity of flow liquid in a pipe.

G.Mounika said: (Dec 21, 2016)  
Pitot tube is used to find out velocity at every point.

Anil said: (Jan 13, 2017)  
It is used to measure pressure so the answer is wrong.

You are right @Jay.

Mahesh Kumar Maurya said: (Jan 21, 2017)  
Pitot tube is used to mearure the velocity of flow.

Kumar Shailendra said: (Jan 25, 2017)  
Pitot tube is used to measured the velocity of flow of liquid.

Lakhwinder Singh Stc Dunera said: (Jan 31, 2017)  
According to Gupta and Gupta it is used to measure stagnation pressure.

Rajani said: (Feb 12, 2017)  
Yeah, pitot tube is used to measure stagnation pressure and the pitot static tube measure Dynamic pressure according to Gupta and Gupta.

Honey said: (Mar 9, 2017)  
Answer is correct, it is used to measure the velocity of flow on the basis of stagnation pressure.

Muniraj said: (Apr 20, 2017)  
Answer C is currect because pitot tube measure stagnation pressure not only pressure. If in option stagnation pressure given then it. S prefer stagnation pressure.

Roshan Jha said: (Jun 27, 2017)  
It is used to measure the velocity of flow on the basis of stagnation pressure.

Praveen said: (Jun 28, 2017)  
Pitot tube is used to measure,

1.Hydrostatic pressure
2. Dynamic pressure
3. Velocity
4. Stagnation pressure

Sachin Singh said: (Jul 17, 2017)  
Pitot tube is used to measure the flow velocity of the fluid.

Ram Krishan Sattwan said: (Aug 28, 2017)  
Velocity of flow is correct. I agree.

Dinesh Kumar Manal said: (Feb 16, 2018)  
Pitot tubes used to measure stagnation pressure.

Leslie Owusu said: (Mar 9, 2018)  
Pitot tube can be used for measuring the velocity head in pipes and in open channels.

Aadarsh Devkate said: (Jun 2, 2018)  
Pitot tube is used to measure velocity head.

Rohit Singh Baghel said: (Jun 16, 2018)  
Yes, pitot tube measured stagnation pressure while pitot-static tube measures both stagnation and static.

Parag Warke said: (Sep 19, 2018)  
Pitot tube measured velocity in pipes and in open channels.

Ahmad said: (Oct 20, 2018)  
Pitot tube measured velocity in pipes b/c it place like that it is opposite to flow liquid so if liquid is at high velocity so they up very high vice versa.

Mayur said: (Dec 31, 2019)  
Pitot tube is used to measure stagnation pressure.

Pitot static tube is used to measure static pressure.

By taking a difference of static and stagnation pressure we get dynamic pressure.

By using Dynamic pressure we can find velocity of flow.

Pranita Dc said: (Jan 3, 2020)  
A pitot tube, also known as pitot probe, is a flow measurement device used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 18th century and was modified to its modern form in the mid-19th century by French scientist Henry Darcy.

Achumi Kits said: (Aug 21, 2020)  
Thanks all for explaining the answer.

Mohd Zaid Sabir said: (Sep 10, 2020)  
A pitot tube is generally used for velocity of the flow.

Avneesh said: (Nov 27, 2020)  
To measure the stagnation pressure.

Ram Pramod Mahato said: (Jan 20, 2021)  
Velocity at stagnation point.

Kavita Choudhary said: (Aug 5, 2021)  
Pitot tube - velocity of pipe.
Hotwire anemometer - velocity of the gas.
Current meter - velocity o0f open-chain flow.
Venturimeter - rate of flow (discharge).
Rotta meter - discharge.
Orifice meter - discharge.
Nozzle meter - discharge.
Elbow/bend meter - discharge.
