Laminar shear
WebbUsing this equation, pressure drop ‘∆p’ in the laminar regime across ‘l’ length of the pipe can be easily calculated. To summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system. Webb20 juli 2024 · For a pipe of length l and pressure difference Δp, the head loss in a pipe is defined as the ratio. hf = Δp ρg = 64 (ρvaved / η)v2 me 2g l d. where we have …
