|Abstract:||This book is the second of two self-supporting volumes that make up the 8th edition of Tables for the Hydraulic Design of Pipes, Sewers and Channels. It provides an alternative solution system for the Colebrook-White equation. The tables in this volume are arranged as follows: Tables C give geometric and hydraulic properties for one hundred and twenty- two characteristic cross sections on a unit size basis. The tables cover pipes and culverts used in drainage and sewerage, irrigation canals and natural watercourses, and the properties are listed for small increments of proportional or relative depths. This latest edition features a more comprehensive coverage of elliptical pipes in horizontal and vertical orientations. There is a revised approach to the treatment of flow resistance in all free-surface circumstances, based on experimental findings. Tables D provide a basic range of solutions for mean velocity V and discharge Q against wide ranges of gradient and against diameter and equivalent diameter sequences covering between 20 mm and 60 mm. These solutions are in terms of mV and mQ, with m as one hundred times the manning coefficient n. Tables E gives values of m to apply to Tables D for solutions of the Colebrook-White equation over the full range of gradients and diameters covered in Tables D, and for a wide range of incrementally varying roughness sizes, this for water at 15° C. A tabular Annexure to Tables E gives expanded treatment for the effect of temperature variations from 15° C within the normal range for water resources and drainage, i.e. 0° C-35° C. A further tabular Annexure gives values of m to apply to Tables D for solutions of the Hazen-Williams formula over the full range of gradients in Tables D and an appropriate range of diameters. Either Colebrook-White, or Manning or Hazen-Williams solutions are made available from Tables D. Also included is a comprehensive list of adjustment factors for discharges for non-tabulated standard diameters, including standard sizes in imperial units. Supporting material is provided, such as expanded explanations of the significance and use of the tables. In addition, there are assessments for fluids with viscosities significantly different from that of water at 15° C. Treatments for uniform, gradually varied and rapidly varied conditions in the crosssections are covered in Tables C. Also included is appropriate material on typical roughness sizes and on additional losses. Format: A4 hardbound, 326 pages|
