Venturimeter is based on Bernoulli's theorem. It consists of a two truncated tubes connected by a pipe at narrow ends. The pipe connecting the two tubes is called throat as shown in figure.

The venturimeter tube is positioned horizontally and the liquid is made to enter in it at end A and after passing through throat BC, it leaves tube at end D. Let at A, the area of cross-section of tube be a₁, pressure of liquid be P₁ and velocity be v₁ And at the throat, the area of cross-section of tube be a₂ pressure of liquid be P₂ and velocity be v₂

In an hour or 60 minutes, the large hand performs a complete circle of 360 degree.  

Therefore, in a time span of 20 minutes or One third of one Hour, you will get 120 degree or 

To find the count of centimeters it is required to move the hand, we first frame the formula i.e. to find the length of the “arc” formed by circular movement of the hand

Therefore, the extremity moves 88 cm in twenty minutes.
