Question

describe a laboratory siphon experiment

Answer 1

Laboratory Siphon Experiment

A siphon is a way to carry water to the uphills by the help of various pipes and pump system by giving required value of flow rate to the pump used. The concept of gravity and atmosphere is being used here and it is being performed in laboratories just told obtain flow rate required for some adequate height given to the pump. The Siphon experiment is a quantitative experiment for calculating the flow of liquid which is based on different laws of liquid flow. Siphon is one of the important and rate experiment based on the liquid flow motion. Various considerations are being taken for this test which are -

• Flow is Directly proportional to time and square to the cross sectional are of the tube used.
• Density of liquid doesn't matter in flow calculation.
• Larger tubes have better efficiency.
• Velocity should be constant weather it ne falling from any height to calculate the flow rate.

There are various advantages of these Siphon experiments and due to that these are preferred very much in judging the laws of liquid motion. It has come to know that these siphon experiments can also be performed in Vacuum conditions. And this would be possible with the help of cohesion and tensile strength among the molecules being used. The required conditions are that the liquid used should be very pure and free of various gases and the surfaces of the pipes should be clean and sufficiently long enough to provide better efficiency.
