For an elevated storage tank , if the minimum allowable pressure = 300 kPa, Height of pipe system at low-pressure service location = 6 m, and head loss from tank to service location: @average daily conditions = 11 m; @peak daily conditions = 14 m. What is the normal operating range for water level in the tank (check classnotes and tank storage section in the book for an example of how to solve this? If this was the elevated storage tank of the neighborhood above, given the amount needed for the service reservoir, what should be the minimal diameter of the above tank? If the neighborhood is built on a flat area, how high should its base be (check fig 3.9, hint - the volume of a cylinder)?
