Question

Calculate the pressure at the middle of a glass jar,40cm tall and filled with Liquid A of density 9000kg/m3​

Answer 1

P = 17658 Pa = 17.658 KPa

Step-by-step explanation:

The pressure applied by a liquid at a given depth is given by the following formula:

`P = \rho gh\\`

where,

P = Pressure = ?

ρ = density = 9000 kg/m³

g = acceleration due to gravity = 9.81 m/s²

h = depth = 40 cm/2 = 20 cm = 0.2 m

Therefore,

`P = (9000\ kg/m^3)(9.81\ m/s^2)(0.2\ m)\\\\`

P = 17658 Pa = 17.658 KPa
