PART VI--PLUMBING AND HYDRAULICS CHAPTER XI RECTANGULAR AND CYLINDRICAL TANKS Water Supply.--The question of the water supply of a city or a town is very important. Water is usually obtained from lakes and rivers which drain the surrounding country. If a lake is located in a section.of the surrounding country higher than the city (which is often located in a valley), the water may be obtained from the lake, and the pressure of the water in the lake may be sufficient to force it through the pipes into the houses. But in most cases a reservoir is built at an elevation as high as the highest portion of the town or city, and the water is pumped into it. Since the reservoir is as high as the highest point of the town, the water will flow from it to any part of the town. If houses are built on the same hill with the reservoir, a stand-pipe, which is a steel tank, is erected on this hill and the water is pumped into it. Water is conveyed from the reservoir to the house by means of iron pipes of various sizes. It is distributed to the different parts of the house by small lead, iron, or brass pipes. Since water exerts considerable pressure, it is necessary to know how to calculate the exact pressure in order to have pipes of proper size and strength. EXAMPLES 1. Water is measured by means of a meter. If a water meter measures for rive hours 760 cubic feet, how many gallons does it indicate? Note.--231 cubic inches = 1 gallon. 2. If a water meter registered 1845 cubic feet for 3 days, how many gallons were used? 3. A tank holds exactl...
