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

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

Constants: g (acceleration due to 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.
