Question

Couette flow is characterized by

Correct answer (D) steady, incompressible, laminar flow between one fixed plate and the other moving with a constant velocity Solution Couette flow is defined as the flow of a viscous fluid in the space between two surfaces, one of which is moving tangentially relative to the other. In its simplest form, it is the steady, incompressible, laminar flow between two infinite parallel plates, where one plate is stationary and the other moves at a constant velocity. Option (A) describes Poiseuille flow in a pipe. Option (C) describes Plane Poiseuille flow (between two fixed plates). Turn this into a strength.
