Sizes of circular reservoirs and estimated cost for various areas of land to be irrigated from windmills (Fuller)
The following table gives the dimensions of circular reservoirs of different capacities ; the quantities of earth in the embankments, if these have inside slopes of three to one and outside slopes of one to one ; the areas which can be irrigated, provided the reservoir full of water is used once in ten days throughout five months and the land receives water to a depth of one foot ; the sizes of mills recommended, and the costs of reservoirs and mills. The lift assumed in choosing the mills is 14 feet: —
