Question

A tank in the form of a cube having edge 0.5 m is filled with water . find thrust on: (i) the vertical wall and (ii) bottom of the container. take density of water = 1000 kg m

Answer 1

Answer:

4900 Pascals or 4.9 kPa

Explanation:

There is a formula:-

Pressure = ρgh

where ρ is the density of the liquid, g is the acceleration due to gravity and h is the height of the liquid column.

Since, the tank is full, h= 0.5 m

ρ =  1000 kg/m³

g= 9.8 m/s²

pressure = 1000*9.8*0.5

= 4900 Pa or 4.9 kPa

Since all sides of a cube are equal and the tank is at rest, the pressure on all walls will be the same, that is, 4900 Pa.
