Fluid Mechanics Viscosity Question 203

Question: A siphon in use is demonstrated in the following figure. The density of the liquid flowing in siphon is 1.5 gm/cc. The pressure difference between the point P and S will be

Options:

A)105 N/m

B)2 × 105 N/m

C)Zero

D)Infinity

Show Answer

Answer:

Correct Answer: C

Solution:

As the both points are at the surface of liquid and these points are in the open atmosphere. So both point possess similar pressure and equal to 1 atm. Hence the pressure difference will be zero.
