ELECTRIC PLANTS ni the pipe is steel) and the other four lines drawn with the sameslope through points which increased in proportion to the head.Another point was computed for a check and the whole work wascomplete. This set of lines represents the actual cost of pipe forvarious diameters for all… … Fig. 11. Even this operation is longer than necessary. We might computethe proper diameter for one head and knowing the law of variationof diameter with respect to head, construct the line which will giveus the proper economical diameter for any head (same pipe or samequantity). For determining the…
