Question

State the factors which determine pressure at a point in a fluid.

Answer 1

1. Pressure at a point in a fluid $=$density of the fluid $\times$acceleration due to gravity $\times$height of the point from the top surface of the fluid.
2. $P=\rho \times g\times h$
3. Pressure at a point in a fluid is directly proportional to the density of the fluid and therefore, the more the density, the more will be the pressure and vice versa.
4. Pressure at a point in a fluid is directly proportional to the height of the point with respect to the top surface of the fluid and therefore, the more the height, the more will be the pressure and vice versa.
5. Pressure at a point is directly proportional to the acceleration due to gravity and therefore, the more the acceleration due to gravity at a place, the more will be the pressure.
