The velocity of the liquid flowing through the divergent portion of a venturimeter
Answer: Option C
No answer description available for this question.
|Santosh said: (Aug 20, 2015)|
|Its wrong. Velocity of the liquid in divergent cone will increase and pressure will decrease.|
|Faisal said: (Dec 21, 2015)|
|Yes, the velocity will increase.|
|Harsha Puwar said: (Feb 20, 2016)|
|Its correct. Velocity decreases.|
|Subham said: (May 12, 2016)|
|@Santosh is correct.
Velocity will increases.
|Debasish Dutta said: (Jun 2, 2016)|
|Velocity increases and the pressure decreases.|
|Raj said: (Jul 9, 2016)|
|You all are absolutely right.|
|Ram said: (Jul 26, 2016)|
|Dev said: (Jan 31, 2017)|
|Discharge remains the same trough out Q= AV.
As the area increases for the diverging section, obviously, velocity will decrease.
|Jitendra Chaudhary said: (Feb 19, 2017)|
|No, pressure increase because the velocity decrease in divergent portion.|
|Hasmukh said: (Apr 28, 2017)|
|As compare to convergent portion divergent area is decrease then velocity is increased. Because divergent angle is 3 to 5 and convergent angle 20.|
|Sambhu Jana said: (Jun 10, 2017)|
|Yes, the velocity increase.|
|Pradeep Gk said: (Oct 11, 2017)|
|In divergent section is acts as diffuser whrere pressure increases and velocity decreases.
As the water enters venturi in the convergent cone where pressure drops and velocity increases (acts as a nozzle) at the throat velocity is very high where the pressure is below the atmospheric after the throat divergent cone is provided in order to regain the loss of pressure so velocity is decreases and pressure increases.
As in case nozzle meter, there is no divergent cone.
|Sachin said: (Dec 15, 2017)|
|How could be velocity increase if area is increasing as q=av but what about pressure it should be increase or decrease.|
|Rahul Gujarati said: (Dec 29, 2017)|
|Liquid flowing through the divergent portion of a venturimeter velocity decreases and for make the energy constant pressure of liquid increases.|
|Harsha said: (Dec 30, 2017)|
|It is not the nozzle they are asking about, It is VENTURIMETER.
Velocity increases and pressure decreases both in convergent and divergent section in case of nozzle and fluid finally comes out with a huge velocity.
But in case of VENTURIMETER which is used to measure the flow in a pipeline, velocity increases and pressure decreases in convergent section and velocity decreases and pressure increases in divergent section.
|Meet Patel said: (Feb 4, 2018)|
|Velocity decreases and pressure increases in divergent section of venturimeter.|
|Pratap said: (Mar 5, 2018)|
|It depends upon the mass of the liquid.|
|Anshul said: (Sep 21, 2018)|
|Yes, velocity will increase in divergent portion.|
|Shailesh said: (Dec 8, 2018)|
|As In divergent part area increasing so pressure decrease & velocity will increase.|
|Pappu Kumar said: (Aug 14, 2020)|
|Velocity will be decrease and pressure will be increase at the divergent portion.|
