# Determine the height of the water level in the water tower if the pressure gauge installed

Determine the height of the water level in the water tower if the pressure gauge installed near its base shows 200pKa and the density of water is 1000kg / m3.

Task data: P (value of water pressure, which is shown by the pressure gauge) = 200 kPa (200 * 10 ^ 3 Pa).

Reference data: g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2; by condition, we take ρ (water density) = 1000 kg / m3.

The water level in the water tower can be expressed from the formula: P = ρ * g * h; h = P / (ρ * g).

Let’s calculate the height of the water level: h = 200 * 10 ^ 3 / (1000 * 10) = 20 m.

Answer: The water level in the water tower is 20 meters.
