The boundary-layer thickness, δ, on a smooth flat plate in an incompressible flow without pressure gradients depends on the freestream speed, U, the fluid density, rho, the fluid viscosity, μ, and the distance from the leading edge of the plate, x. (a) Express these variables in dimensionless form and (b) calculate dimensionless parameter (proportional to x) with x = 0.142 m, rho = 225 kg/m3, U = 0.133 m/s, μ = 0.2 × 10-4 N-s/m2.
