Bernoulli’s principle states that speed of moving fluid increases when the pressure within fluid decreases
Bernoulli’s formula –
p + 1/2(ρV2) + (ρ x g x h) = constant
In above formula of Bernoulli’s equation,
p = Pressure
ρ = Density
V = Velocity
h = Elevation
Example –
I. Venturimeter
This is restriction type flow meter. Venturimeter works on Bernoulli’s principle. Venturi converts pressure energy into kinetic energy. It helps to calculate flow energy at discharge.
As we see in diagram 10.1.2, Venturimeter consist following parts
a) Converging cone
b) Throat
c) Diverging cone
d) Manometer
Notations in diagram
a) D = Diameter of first pipe
b) D = Diameter of second pipe
c) P1 = Pressure at first pipe
d) P2 = Pressure at second pipe
e) h = Manometric deflection
Applications pf venturimeter,
a) It is widely used in waste water treatment
b) It is also used to measure fluid velocity
