Question

Why is water flowing through a horizontal pipe inflow at the narrowest part of the pipe?

Answer 1

Bernoulli’s principle developed by physicists states that because the speed of a moving fluid will increase (liquid or gas), the pressure among the fluid decreases. Although Bernoulli deduced the law, the Euler United Nations agency derived Bernoulli’s equation in its usual form within the year 1752.

Complete step by step answer:
Bernoulli’s Principle : The total energy of the moving fluid comprising the attraction Potential energy of elevation, the energy associated with the fluid pressure, and thus the energy of the fluid motion, remains constant.
Bernoulli’s Principle Formula is given by
$\text{P }+\text{ }\dfrac{1}{2}\rho v{}^\text{2}\text{ }+\text{ }\rho gh\text{ }=\text{ }Constant$.
where v is speed, P is pressure and $\rho$ is density of flowing liquid.
Bernoulli’s equation formula might be a relation between pressure, energy, and attraction P.E. of a fluid during a very instrumentality.
According to Bernoulli’s theorem
$~\dfrac{P}{\rho }\text{ }+\text{ }\dfrac{1}{2}v{}^\text{2}\text{ }+\text{ }gh\text{ }=\text{ }Constant$
Where,
• p is that the pressure exerted by the fluid
• v is that the speed of the fluid
• ρ is that the density of the fluid
• h is that the peak of the instrumentality
Bernoulli’s equation offers nice insight into the balance between pressure, rate, and elevation.
Water is flowing through a horizontal pipe inflow at the narrowest part of the pipe because the speed is maximum at the narrow part of the pipe and pressure is low in order to maintain the conservation of energy according to Bernoulli’s Principle.

Note: Bernoulli's principle relates the pressure of a fluid to its elevation and its speed. Bernoulli's equation is used to approximate these parameters in water, air, or any fluid that features a terribly low body.
