Comments
Hydrants opened all the way.
For method of calculating picot flow with a red Pollard diffuser: see eq. 13, Walski and Lutes article 199D Journal Management and
Operations AW WA. For yellow Pollard diffusers, a best fit third order polynomial equation of the Pollard flow vs. Fund pressure gauge is
used.
Estimated Consumption (gal) 2493
For use for water audit
