Many cities have water tanks raised high off the ground to produce pressure for their residence. If one such water tank had a diameter of 4.80 m and its water level being 24.2 m above the ground. What would be the pressure at ground level if the water was not being used? (static) If at ground level a faucet had an opening with a diameter of 2.80 cm, how fast would the water come out of the faucet?
