内容説明
This new book and diskette provides detailed instructions on how to find and implement the lowest cost pipe combinations for water distribution systems. It also provides steady state and extended period simulation, as well as fundamentals of pipe sizing. This book and program (WADISO-Water Distribution Simulation and Sizing) are the only tools needed for solving pipe size based on cost. Written by experts at the water plant and the university, it's practical, easy-to-use, and a time-saver. All water utility personnel, water consultants, and university professors will find Water Distribution Systems to be invaluable.
