Q1: Find the boundary layer thickness (6) equation, the shear stress (to) and the
coefficient of drag (C₁) if the velocity distribution in the laminar boundary layer over the
face of a spillway was observed to be:
u
7- (C)-()*+C)*.
U
Then calculate the boundary layer thickness and drag force if the air flows over a sharp
edged flat plate 0.25m long and 0.5m wide at a velocity 1 m/s, take the air density 1.23
kg/m³ and the kinematic viscosity is 1.46*10-5 m/s².
