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. The Hazen–Williams equation has the advantage that the coefficient C is not a function of the R… WebThe Modified Hazen-Williams C factors must be obtained separately for all the pipes in the network. Step 4. Export this table to Excel using either Export to File or Copy with Headers and Paste In Excel, create a new column like New HW C.
