Answer 1

Concept:

Pressure head:

Pressure head is the vertical height of a fluid column that corresponds to a specific pressure exerted by the fluid.

Mathematically, it is given as: \(h = \frac{P}{ρ g}\)

Where, P is pressure, ρ is fluid density, and g is acceleration due to gravity.

Hence, pressure head is best described as the height of a fluid column equivalent to the pressure exerted by the fluid.
