In Case Of Laminar Flow Of Fluid Through A Circular Pipe, The----------?

In Case Of Laminar Flow Of Fluid Through A Circular Pipe, The----------?

Shear Stress Over The Cross-Section Is Proportional To The Distance From The Surface Of The Pipe

Average Flow Occurs At A Radial Distance Of 0.5 R From The Centre Of The Pipe (R = Pipe Radius)

Velocity Profile Varies Hyperbolically And The Shear Stress Remains Constant Over The Crosssection

Surface Of Velocity Distribution Is A Paraboloid Of Revolution, Whose Volume Equals Half Thevolume Of Circumscribing Cylinder

Q1 = Q2 = Q3

V1 = V2 = V3

Q = Q1 + Q2 + Q3

F = F1 + F2 + F3
