Bernoulli 's veterm is a currental principla in fluid dynamics that relates thee pressure, velocity, and hight in a moving fluid. It is used to calculate pressure differences with in fluid systems, such as pipes, chandels, and open fairs. Understanding how to appley Bernoulli' s thevocm helps in designing contriment fluid systems and analyzing flow behavor.
Bernoulli 's Theorem overview
Te thevow states that for an incompressible, steady flow of a fluid with negagible vissity, thee sum of thee pressure energiy, kinetik energiy, and potential energity estanes constant along a eleadline. This actulship allows contraers to determinate pressure differences based on changes in velocity and height.

Te Bernoulli equation is expressed as:
CLAS1; CLAS1; CLAS3; CLAS3; P + ½ CLAS3; P + ½ CLAS3m v ² + CLAS3f h = constant CLAS1; CLAS1f; CLAS3f: 1 CLAS3f; CLAS3f;
Where pressure 1; FLT: 0 CLAS3; FLT: 0 CLAS3; PLAS1; FLT: 1 CLAS3; is pressure, CLAS1; FLT: 2 CLAS3; FLT: 1; FLT: 3 CLAS1; FLT: 3 CLAS3; is fluid density, CLAS1; FLT: 1; FLT: 4 CLAS3; CLAS3; FLAS3; FLAS1; FLT: 5 CLAS3; FLAS3; is velocity, and CLAS1; FLT: 6 CLAS3; CLAS3; g CLAS1; FLAS1; FLAS1; FLAS3e; FLAS3e; is accuPLASECUS01e.
Appliying thee Equation
To find thee pressure difference between even two point in a fluid system, remegine thee Bernoulli equation:
CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O3; CLAS3O4; CLAS3O4; CLAS3O4; CLAS3O4; CLAS3O4; CLAS3O4; CLAS3O4; CLAS4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E4E3E3E3E3E3E3E3E3E3@@
This formula accounts for changes in velocity and heigt, proving thee pressure difference between een point s1 and2.
