Velocity distribution in a boundary layer is given by u / u∞ = sin((π/2)(y/δ)), where u is the velocity at vertical coordinate y, u∞ is the free stream velocity and δ is the boundary layer thickness. The values of u∞ and δ are 0.3 m/s and 1.0 m, respectively. The velocity gradient (∂u/∂y) (in s-1, round off to two decimal places) at y = 0, is _______.
Correct : 0.45 to 0.49
