Siphon will fail to work if

[A]. the densities of the liquid in the two vessels are equal
[B]. the level of the liquid in the two vessels are at the same height
[C]. both its limbs are of unequal length
[D]. the temperature of the liquids in the two vessels are the same

Answer: Option B

Explanation:

No answer description available for this question.

Both the vessel has a liquid has a same heigt then the liquid are of the same desity, then work done will be zero.

What is siphon?

Sundar said: (Mar 22, 2011)  
Siphon: Draw off or convey (liquid) by means of a siphon

Yogesh said: (Mar 31, 2011)  
Actually I also get confused, What is Siphon.

Mohit Shah said: (May 25, 2011)  
A siphon is a tube which can be used to move water from a reservoir to another point.

A siphon is a tube which is used to move water from a reservoir to another vessels point.

Swathi said: (Jun 8, 2011)  
A tube shaped like an inverted V OR U with unequal legs .It is used to convey liquid from a container to a lower level by atmospheric pressure.

Vasu said: (Oct 22, 2011)  
Due to gravitational force every object attract to downwards. When they are equal at vessels no applying gravitational force, so there is no flow from top to bottom.

Please explain the siphon theory.

What is Siphon?

Atalay said: (May 31, 2012)  
Give brief explanation about siphon and its theory?

Nirosha S said: (Aug 17, 2012)  
What is mean by siphon?

Vinay Kumar said: (Nov 16, 2012)  
If two limb of siphon have equal height of water then the atmospheric pressure equal on both limb of siphon hence water will be not flows from one side to another.

Dinesh Kumar Meher said: (Jun 21, 2013)  
A siphon is a bent tube generally used to draw off liquid from one container to another container, which must at lower level. Thus the answer is B.

Timothy said: (Jul 24, 2013)  
A siphon is a tube or conduit bent into legs of unequal length, for use in drawing a liquid from one container into another on a lower level by placing the shorter leg into the container above and the longer leg into the one below, the liquid being forced up the shorter leg and into the longer one by the pressure of the atmosphere.

What is siphon precisely?

Kalpana Vasanth Gowda said: (Nov 12, 2013)  
Siphon action is mainly due to atmospheric pressure in a reservoir through inverted U tube(liquid upfill). So when both the reservoirs at the same liquid length siphon action fails due to equal atm pressure.

What is siphon?

Pranshyagarwal said: (Jan 10, 2014)  
What is mean siphon?

Bhavana said: (Jan 25, 2014)  
I guess that siphon fails to work if the level of the two containers are at same level. Because, when both the containers are at same level the liquid in both containers stop sending the liquid from each other.

Pravin Gaikar said: (Jan 27, 2014)  
A siphon is a tube which is used to move water from a reservoir to another vessels point.

Sourav Mukherjee said: (May 7, 2014)  
Siphon is a mechanism, which is based on the pressure difference between a horizontal pipe connected to two vertical pipe. The smaller pipe is dumped in the liquid and other end is opened to the reservoir.

Kelvin Sweetbert said: (Jun 16, 2014)  
Where does these legs of a siphon appear while siphon is a tube.

Mounika said: (Jun 26, 2014)  
Because from high pressure to low pressure the phenomenon of siphon works so at the same height it does not work.

Dianah said: (Aug 29, 2014)  
A siphon is a bent tube that is used to draw water from a reservoir to another tank at a point.

Emmanuel said: (Sep 30, 2014)  
A siphon is a tube which has two unequal limbs used to draw liquid of different heights in the vessels involved mainly two provided that the density and temperature of the liquid in the two vessels are the same.

Armaan Mallik said: (Nov 10, 2014)  
Siphon helps us to carry water from one tube to another.

Pratik said: (Mar 9, 2015)  
Siphon is a long bent pipe carry water from one reservoir to another reservoir when both reservoir separated by hill or higher elevation. It is generally inverted V shaped structure.

Anurag said: (Sep 24, 2015)  
Try to explain everything.

Navaneeth said: (Apr 3, 2016)  
In the question, if in the two containers there is the same amount of liquid, then the liquid will not be able to flow into either container as there is an equilibrium as in heat.

If there is an equilibrium of temperatures in both objects, heat will not flow same happens here. I think it is correct.

Is it working on moon?

Ssn said: (Nov 4, 2016)  
Where the siphon used mostly?

Ishaq said: (Dec 4, 2016)  
Bernoulli law.

Satvik said: (Jan 27, 2017)  
The reason is if you took the vessels at the same level the pressure gradient across the.

Siphon tube would vanish.

Ali said: (Jun 16, 2017)  
Please explain the siphon theory.

Jagga said: (Aug 17, 2017)  
Ewc is an example for siphon. When the level of water is equal there will be no flow.

Jackson said: (Aug 30, 2017)  
And, if the long tube be cut what can happen to siphon?

Hollet Junior said: (Nov 14, 2017)  
Siphon will work best if the end of the siphon is dipped into a greater depth than the upper part.

Cele said: (Dec 3, 2017)  
Where is siphon applied?
