Subject: Hydrant Water Flow Test Results
Mark
Hi, here are the results of the hydrant water supply test performed at 4837 Azeiia Ave North in Brooklyn Center. The
test was performed on August 7"'. The hydrant south of the entrance to the 4837 property was used to read static and
residual pressure. The hydrant to the north of the entrance to the 4837 property was flowed. Flow was through a 4.5
in. hydrant butt and resulted in a pitot reading of 27 psi.This reading translated into a flow of 3150 gpm. Adjusting this
flow by a coefficient of 0.80(3150 X 0.80=2520 gpm)a flow of 2520 gpm was observed. The resulting residual pressure
observed was 30 psi and a static pressure of 60 psi was also observed.
Thank you again for your assistance in completing this test. Please let me know if you have any questions.
Regards,
Keith Erickson
