1. Blasius proposed a formula for wall shear stress (Tu) at a distance x from the leading edge in viscous flow flowing past a flat plate with velocity V, that

can be rewritten as \tau_{w}=k \rho v^{\frac{1}{2}} V^{\frac{3}{2}} x^{-\frac{1}{2}} where v is the kinematic viscosity given by v = µ/p. Determine the dimensions of the constant k (if any).
