Typical towns in states with big plains like Texas need an elevated tank to supply tap water. Below there is a picture of a typical elevated tank. If we approximate the tank as a cylinder with a diameter of 50 ft and a height of 25 ft, answer the following questions: Bernoulli s Equation (12 . 1) and Conservation of Mass (6 . 1) 3. Finally, estimate the time to empty it if the mean flow velocity at the discharge pipe is governed by the formula derived in part 2 (see below). Again, the discharge pipe has a 12 in. pipe diameter and the water level is initially at 250 ft above ground and the water level is initially at 250 ft above ground. Note: The elevated tank empties at 225 ft.
