Abstract:
This report gives information relating to the selection
of pipe sizes and design of distributing systems for
adequate supply of water in buildings. It contains flow
charts showing the capacities of different commercial
sizes of pipe in terms of friction loss in head for four
degrees of roughness, depending on the pipe material and
the character of water with which the pipe is used. A
practical procedure is developed for the economical
selection of pipe sizes for the different demands for
each part, depending on the estimated demand and on the
pressure available for friction loss as computed for
particular service conditions. Suggested variations in
the procedure provide convenient means of allowing for
decrease in capacities of pipes in service.
