Question:
Pressure head in Bernoulli's equation is
Pressure head in Bernoulli's equation is
Updated On: Jul 28, 2022
- $\frac{P_{\rho}}{g}$
- $\frac{P}{\rho g}$
- $\rho g$
- $P\rho g$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Bernoulli's equation is
$P+\rho gh+\frac{1}{2}\rho v^{2}$ = a constant,
or $ \frac{P}{\rho g}+h+\frac{1}{2} \frac{v^{2}}{g}$ = constant,
Here, $ \frac{P}{\rho g}$ is called pressure head.

Concepts Used:
Bernauli Theorem
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738.
