Question

3. Air at 1 atm and 20 0 C flows tangentially on both sides of a smooth flat plate of width W=10 ft and length L=10 ft in the direction of flow (x-direction). The velocity outside the boundary layer is constant at 20 ft/s. a) What is the laminar boundary layer thickness at x=1 ft? b) The boundary layer varies as x to what power? c) If the plate is 100 ft long, does the boundary layer thickness change at 1 ft?

Answer 1

ExplanationAir at 1 atm and 20°C flows tangentially on both sides of a thin, smooth flat plate of ... ... Smooth Flat Plate Of Width W = 10 Ft, And Of Length L 3 Ft In The Direction Of The Flow. The Velocity Outside The Boundary Layer Is Constant At 20 Ft/s.
