So in this case the pressure drop is proportional to the viscosity μ. However at high flow rates the pressure drop is given by the Darcy-Weisbach equation: Δ P = f d ℓ 2 r ρ v 2 2. where ρ is the water density, v is the flow velocity and f D is a fudge factor ...

WebApr 6, 2024 · We expect the pressure drop to be 1 over (⅔)^4.9 or about 7 times higher than the original pipe. At 0.3 gpm, the pressure drop is 3 inches. That’s about 6 times the original. At 0.6 gpm, the pressure drop is 7.5 inches, about 7 times the original. And at 0.9 gpm, we’re off the scale. WebJun 13, 2024 · Streamgaging generally involves 3 steps: 1.
