Combination of Variables. A boundary layer expert uses a combination of variables n= ay/x¹/2 together with = bx¹/2 f(n), where a and b are constants. It is found that for flow of air near a flat plate f(n) = 0.3n². If a = 1000 and b = 0.001, compute (a) the shear stress at the plate in air at x = 50cm; (b) the air velocity at y = 0.1mm and x = 50cm; (c) the total drag force, FD, on a square plate L = W = 4m. Ans OM: (a) t: 10-2 Pa; (b) u: 10-2 m/s; (c) FD:10-¹ N
