| **The water level in the water tower is 25 m above the ground. What is the water pressure in a pipe connected to the tower and located at a depth of 5 m from the surface of the earth?**

These tasks: h1 (water level in the considered water tower relative to the ground) = 25 m; h2 (pipe depth relative to the ground) = 5 m.

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

The water pressure in the pipe is determined by the formula: P = ρw * g * h = ρw * g * (h1 + h2).

Let’s calculate: P = 1000 * 10 * (25 + 5) = 300 * 10 ^ 3 Pa (300 kPa).

Answer: The water pressure in the pipe is 300 kPa.
