Flow area equation
WebThe Equations. This flow calculator uses the Hazen Williams equation to solve for flow assuming that the pressure at the outlet is zero (open to atmosphere) and thus the entire pressure at the hose bib is dissipated by friction losses in the hose. The pressure at the hose bib is assumed to be the dynamic pressure (while water is flowing) not ...
