An element for sensing local shear stress is positioned in a flat plate 0.40 meter from the leading edge. the element simply consists of a small plate, mounted flush with the wall, and the shear force is measured on the plate. the fluid flowing by the plate is air with a free-stream velocity of 30 m/s, a density of 1.2 kg/m3 and a kinematic viscosity of 1.5 × 10-5 m2/s. the boundary layer is tripped at the leading edge. what is the magnitude of the force due to shear stress acting on the element?
