Pressure head in Bernoulli's equation is:

A$$\displaystyle \frac { P\rho }{ g } $$
B$$\displaystyle \frac { P }{ \rho g } $$
Correct Answer
C$$\displaystyle \rho g$$
D$$\displaystyle P\rho g$$

Solution

Bernoulli Equation is principally conservation of energy equation in fluids, relating the pressure, velocity of fluid flowing and gravitational potential of liquid at some point.

It is given as

$$\dfrac{P}{\rho g}+h+\dfrac{1}{2} \dfrac{v^2}{g}=constant$$

where $$\dfrac{P}{\rho g}$$ is the pressure head.
