# Bernoulli’s Equation (Kinematics and Dynamics of Flow Part-5)

### Applications of Bernoulli’s Equation

#### Venturimeter: With the help of this instrument rate of flow of fluid is measured through the pipe.

##### If in equation, we use the differential U-tube manometer to give the value of h, then it is given by

where x is the difference of heavier column in U-tube

Hg is liquid filled in manometric tube

L is the liquid flowing inside venturimeter

#### Pitot Tube: With the help of this instrument the velocity of flow at any point in pope or channel can be measured.

It consists of a glass tube bent at a right angle.

It works on the principle that: If velocity of flow at any point becomes zero, then the pressure is increased at that point because kinetic energy converts into pressure energy.

Now applying Bernoulli’s equation between points 1 & 2.
