Text: The water level in a tank is 20 m above the ground. The tank's hose is connected to the base, and at the end of the hose is attached the sprinkler, which sprays water upwards. The lid of the tank is airtight and does not leak, and the air pressure above the water surface is 2 atm (200 kPa) (as effective pressure). Find the maximum height the water can reach from the fountain. Neglect any losses in the system.
