The design of small water systems requires the application of basic hydraulic principles. To prevent excessive head losses in piping systems created by pyramiding peak flows, the Cross method of successive approximations is used. This is a relatively simple means of checking the ability of the system to supply an adequate quantity of water at sufficient pressure. An example problem is worked out in detail to show how the method is applied to a trailer coach park water distribution system. Hydropneumatic storage tanks do not operate at maximum efficiency without prepressuring. Since Boyle's Law is applicable to all gases including air, it is used to determine the amount of prepressuring required to obtain the greatest amount of water from storage between pump cycles at predetermined pressure settings. A graph has been developed to determine the volume of water in a tank at various levels of prepressuring.
