Apr 8, 2020 at 10:49 comment added Chet Miller The formula you gave is valid only for laminar flow. For the situation you described the flow is going to be turbulent, and the formula will give the incorrect results. See Transport Phenomena by Bird, Stewart, and Lightfoot to learn how to determine the pressure drop-flow rate relationship for turbulent flow.
