# Determine the water pressure at the bottom of the bath, if the height of the water column is 0.4

Determine the water pressure at the bottom of the bath, if the height of the water column is 0.4, and its density is 1000 kg / m3

Initial data: h (height of the water column in the bathroom) = 0.4 m.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2; according to the condition ρw (density of water in the bathroom) = 1000 kg / m3.

The pressure that the water column will exert on the bottom of the bathtub is determined by the formula: P = ρw * g * h.

Calculation: P = 1000 * 10 * 0.4 = 4 * 10 ^ 3 Pa (4 kPa).

Answer: At the bottom of the bath, a column of water exerts a pressure of 4 kPa.
