question

A liquid (\rho = 62.4 lb/ft^3 and \mu = 7.5 × 10^-4 lb/ft-s) flows past a flatplate with a free-stream velocity of 12 ft/s. For a point at adistance of 2 in. from the leading edge of the plate, determine: a)thelaminar boundary layer thickness. b)theshear stress. c)theshearforce per unit width of flow, acting on the plate betweenthe leading edge and the given point.
