| **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.
