Question

The pressure caused by a column of liquid is calculated using the equation___

• A. p = ρgh
• B. p = ρgm
• C. p = $\frac{\rho g}{h}$
• D. p = $\frac{\rho h}{g}$

Answer 1

The correct option is A

p = ρgh

The pressure caused by a column of liquid can be calculated using the equation:

pressure = height of column × density of the liquid × gravitational acceleration

Where,

pressure (p) is measured in pascals (Pa)

height of column (h) is measured in metres (m)

density (ρ) is measured in kilograms per metre cubed (kg/m³)

gravitational field strength (g) is measured in m/$s^2$
