An incompressible, Newtonian fluid is flowing through a vertical circular conduit (a pipe). The flow is laminar.
What is the velocity at the inner wall of the pipe? How do you know?
The pipe has diameter a. The velocity profile in the pipe is vz = b – c r2. Please express c in terms of a and b. (You are applying a boundary condition to solve this problem.)
Where in the pipe is the velocity a maximum?
Please express the maximum velocity in terms of a and b.
What is the average velocity in the pipe in terms of a and b?
Express the volumetric flow rate in terms of a and b.
