Step 1

1 of 3On page 185 of the book, we get the concept of Bernoulli's principle, which states that the use of pressure and kinetic energy per unit volume of a flowing fluid must be constant. Mathematically expressed as,

$P + \frac12 \rho v^2 = \text{constant} \hspace{0.5 cm} (1)$

where $P$ are the pressure, $\rho$ is the density of the fluid, and $v$ is its velocity.
