[amp_mcq option1=”h” option2=”wh” option3=”$$\frac{{\text{w}}}{{\text{h}}}$$” option4=”$$\frac{{\text{h}}}{{\text{w}}}$$” correct=”option3″]
The correct answer is: $\boxed{\text{B}. wh}$.
The pressure intensity at a point in a fluid is given by the following equation:
$$P = \rho g h$$
where:
- $P$ is the pressure intensity,
- $\rho$ is the density of the fluid,
- $g$ is the acceleration due to gravity, and
- $h$ is the depth of the point from the surface.
The specific weight of a fluid is given by the following equation:
$$\gamma = \rho g$$
Therefore, the pressure intensity at a point in a fluid can be written as:
$$P = \gamma h$$
or, in this case,
$$P = wh$$
