5. Free flow rate is U = Find the thickness of the boundary layer at the end of the long plate 6 m long when 4 m/s. Use A and B to show drag when the fluid is 20°C air (v=1x10^-5 m^2/s. p=1.22kg /m^3) and has a width of 4 m. Use 5X10^5 for the critical Reynolds number. (However, d=5 √(vx/U). Local surface friction coefficient cf=Ax^-1/2 in the laminar flow boundary layer and 6-0.38√(v/ U∞)^1/5 *x4/3 Local surface friction coefficient of =Bx^-1/5 in the turbulence boundary layer) (PO-05, L-3, allocation of 10)
