What pressure does mercury put on the bottom of the vessel? The height of the mercury in the vessel is 15 cm

Initial data: h (height of mercury in the vessel) = 15 cm.

Reference values: ρр (density of mercury) = 13600 kg / m3; g (acceleration due to gravity) = 10 m / s2.

SI system: h = 15 cm = 15 * 10-2 m = 0.15 m.

The pressure that mercury will exert on the bottom of the vessel is calculated by the formula: Р = ρр * g * h.

Let’s calculate: P = 13600 * 10 * 0.15 = 20 400 Pa or 20.4 kPa.

Answer: At the bottom of the vessel, mercury will exert a pressure of 20.4 kPa.
