# Worksheet: Hydrostatic Pressure

In this worksheet, we will practice calculating the hydrostatic pressure acting at a given depth of liquid from the density and strength of gravity.

Q1:

Which of the following is the best general definition of hydrostatic pressure?

• AThe buoyant force due to a difference in density between a suspended solid and the surrounding fluid
• BThe average pressure exerted by a moving fluid on the walls of its container
• CThe pressure exerted by a fluid on a point within or on the boundary of the fluid
• DThe internal stress on a suspended object at the lowest point in the surrounding fluid
• EThe total weight of a fluid

Q2:

Which of the following is the correct expression for hydrostatic pressure?

• : hydrostatic pressure
• : height of the liquid
• : density of the liquid
• : acceleration due to gravity
• A
• B
• C
• D
• E

Q3:

How tall does a column of mercury need to be to exert a pressure of 1 atmosphere at its base? Take the density of mercury as 13.6 g/mL and acceleration due to gravity as 9.81 m/s2.
