A fluid with a Reynolds number of 50,000 is flowing over a flat plate. Determine whether the flow is laminar or turbulent, and explain your reasoning.
💡 Hint: Refer to the critical values of Reynolds number.
Given a velocity field described by the equation u = U(1 - y^2/h^2), derive the expression for wall shear stress at the boundary y = h.
💡 Hint: Remember to calculate the partial derivative with respect to y.
