Hazen williams equation excel
WebThe Hazen-Williams Equation is also suggested by ASHRAE as one of the methods to calculate pump head. However, it is applicable to water only which is not a problem for HVAC chilled water pumps and condenser water pumps. The Hazen-Williams Equation for piping head loss is as follow: HL = (10.67 x Q 1.852) ÷ (C 1.852 x D 4.8704) where, WebJan 1, 2014 · Darcy-Weisbach and Hazen and Williams equations typically estimate friction head loss. The friction factor depends on Reynolds number and relative roughness of the pipe. Total head loss includes ...
