Acrude approximation for the x-component of velocity in an incompressible laminar boundary layer flow is a linear variation from u = 0 at the surface (y = 0) to the freestream velocity, u, at the boundary layer edge (y = δ). the equation for he profile is u = uy/δ, where δ = cx1/2 and c is a constant. show that the simplest expression for the y component of velocity is v = uy/4x. evaluate the maximum value of the ratio v /u, at a location where x = 0.5 m and δ = 5 mm.

Several mountains together form a mountain . a few of these combined form a mountain system. several systems combined form a mountain , which can stretch thousands of miles in length.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
