WebHydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum.. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a … Web5 mrt. 2024 · Figure 7.14-2: Pure carrier liquid in an inclined pipe. Figure 7.14-2 shows the driving force and resisting shear stresses in the pipe. The shear stress, in general, is defined by, based on the Darcy Weisbach equation: (7.14.2) τ = λ l 8 ⋅ ρ l ⋅ v l s 2. The hydraulic gradient can now be determined with: fire in the blood movie watch online
