📌Some stress distributions in hydraulics

▪Direct Stress Distribution is Uniform At sections Reasonably Away from Point of application of load.

▪Bending stress Distribution is Linear being zero at Neutral axis & maximum at extreme Fibres.

▪Transverse shear stress (Tangential stress) Distribution is Parabolic being Zero at extreme Fibres & Maximum at Neutral axis.

▪Torsional Shear stress Distribution is Linear being zero at neutral axis and Maximum at extreme Fibres.

▪In Turbulent Flow velocity profile is logarithmic.

▪In Laminar Flow velocity profile is Parabolic.

▪Laminar Sublayer Exist In Turbulent zone and the velocity profile in Laminar Sublayer is Parabolic.

▪Shear stress distribution is linear in both Laminar and Turbulent flows.

▪Average shear Stress Distribution is always Uniform (rectangular).

▪Average velocity distribution is always Uniform in both Laminar and Turbulent Flow situations (rectangular).
