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

  1. 10 to the power of 5 N divided by m
  2. 2 cross times 10 to the power of 5 straight N divided by straight m
  3. zero
  4.  Infinity

The correct answer is: zero


    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.
