For the laminar flow through a circular pipe
WebQuestion: When a Newtonian fluid flows under steady, laminar condition through a circular pipe of circular constant diameter, which of the following is NOT a correct conclusion? (a) The velocity will decrease along the length of the pipe (b) The velocity gradient at the centerline of the pipe is zero (c) The shear stress at the centerline of the … WebLaminar flow is a flow regime characterized by high momentum diffusion and low momentum convection. When a fluid is flowing through a closed channel such as a pipe or between two flat plates, either of two types of flow may occur depending on the velocity and viscosity of the fluid: laminar flow or turbulent flow. Laminar flow occurs at lower ...
