Calculate the height of the concrete wall producing 220 kPa for the foundation.

Calculate the height of the concrete wall producing 220 kPa for the foundation. The density of concrete is 2300kg / m3.

Initial data: P (pressure that the concrete wall produces on the foundation) = 220 kPa = 220 * 10 ^ 3 Pa.

Constants: g (acceleration of gravity) = 10 m / s2; according to the condition ρ (concrete density) = 2300 kg / m3.

The height of a concrete wall can be determined from the following formula: P = F / S = m * g / S = ρ * V * g / S = ρ * S * h * g / S = ρ * h * g, whence h = P / (ρ * g).

Let’s calculate: h = 220 * 10 ^ 3 / (2300 * 10) = 9.57 m.

Answer: The height of the concrete wall is 9.57 meters.
