AB is 148 feet long, is 1-1/4" type M copper pipe with a gate valve and has a flow rate of 20 gnm there is no entrance loss. Section CB is 176 feet long, is 2"type L copper pipe with a swing check valve (instead of the balancing valve shown)and has a flow rate of 70 gnm Section BD is 158 feet long, is 2-1/2" schedule 80threaded steel pipe with two 90° elbows, an exit and has the flow rate to be determined by the continuity equation. Remember that section BD has a straight thru tee and CB has a branch tee. Instead of making the theoretical calculations, you are to use the equivalent length information provided in Appendix C on page C-11. In addition, use the charts on pages C-13 & -14 for copper pipe and the chart on C-16 for the steel pipe. Complete the following table to determine: 1. The head loss in each section (ft. w.c.). 2. The total system head loss and indicate if it is ABD or CBD (ft. w.c.).
