Question 13During the analysis of fluid flow, we are more often interested in obtaining the averagevelocity, and one of the common ways of obtaining the average velocity is to take an averageacross the flow cross-section. This is called area-average velocity, average along the directionparallel to the principal direction of flow.A) TrueBFalse

The cross-section should be perpendicular to the principle direction of flow

During the analysis of fluid flow, we are more often interested in obtaining the elocity, and one of the common ways of obtaining the average velocity is to take a cross the flow cross-section. This is called area-average velocity, average along the arallel to the principal direction of flow. A) True B) False

A Newtonian fluid with absolute viscosity (Greek mu) flows past a flat surface. Due to the no-slip boundary condition, the velocity profile, u(y), develops near the surface and is given by u/U (shown in image provided) where the constant parameters U and delta have dimensions of velocity and length respectively.a) Develop an expression for the shear stress acting in any horizontal plane.b) Determine the shear stress acting on the surface at y = 0 and again at the edge of the boundarylayer, y = delta. (Express your answers in terms of Greek mu, the outer velocity U, and the boundary layer thickness delta.)
