Water flows over both sides of an immersed flat plate of length 0.8 m and width of 0.3 m. The flow is laminar throughout and the plate is smooth. For the water properties, assume v=1.0×10⁻⁶ m²/s and rho=1000 kg/m³. 5.1.
If the total drag force acting on the plate is 0.13 N, calculate the free stream velocity of the flow, U, using the Blasius exact solution.
