Not illustrated. 1886 Excerpt: ...of considerable size, and will constitute a most valuable addition to our store of knowledge in this important branch of the science of Hydraulics. This conduit, except through hard rock tunnels, is built of well-formed hard brick, with good mortar joints; its general section is shown by the following sketch, the bottom invert having a radius of 13.22 feet, and a chord of 8.29 feet; its original section has been changed only very slightly by settlement, and there are very slight gains or losses by infiltration or leakage along its course; the curves of the sections experimented upon have a minimum radius of 1433 feet; its general inclination is 1 foot per mile. The discharge, or Q, was for Experiments Nos. 391 to 446 (except for No. 443) measured by the flow over a weir, 19 feet long, whose co-efficients of discharge with various heads, had been determined with great exactness by direct measurement;t this weir was placed at the upper end of the conduit. Most of the experiments were made with sections of the conduit only a short distance below the weir, so that only very slight corrections were required in any experiment for gains by infiltration or losses by leakage. These corrections were determined by actual measurement, when no water was flowing through the conduit. The head h, or surface inclination, for all the experiments was ascertained by Transactions of Am. Soc. C.E.; January, February and March, 1883. t The experiments with this weir, where Q was directly measured, are given in the Chapter on Weirs; our Weir Nos. 9 to 16 inclusive. establishing two bench-marks, one at the upper and the other at the lower end of the longitudinal section; a dam was placed below the lower bench-mark, the flow of water suspended in the conduit, and the difference in e...
