Head Loss in Pipe Systems Laminar Flow and Introduction to Turbulent Flow

Analytical Solution for Laminar Flow (7) Total flow rate is Q = πR2V c 2 = πR2 2 D2 16µ „ − dp dx « = πD4 128µ „ − dp dx « Now, for convenience define ∆p as the pressure drop that occurs over a length of pipe L. In other words, let − dp dx ≡ ∆p L Then Q = π
