Hazen–Williams equation - Wikipedia

The Hazen–Williams equation is an empirical relationship which relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems such as fire sprinkler systems, water supply networks, and irrigation systems. It is named after Allen Hazen and Gardner Stewart Williams.

This paper presents hydraulic simulation of canal reaches and structures of Lower Bari Doab Canal for effective canal management and operations to improve the performance of an irrigation system. The roughness coefficient of different canal reaches and calibration parameters for inline and …

IOP Conference Series: Earth and Environmental Science

A degradable polymeric composite was prepared from polyethylene (PE) and breadfruit leaves tree powders. Breadfruit leaves tree powders were mixed with PE in an internal mixer at a temperature above the glass transition of PE without additives. Formulations were based on PE/leaves ratio of 100/0, 90/10, 85/15, 80/20 and 75/25 on a dry weight basis.
