A smooth flat plate is aligned parallel to a uniform stream of airflow. Given, the air density, p = 1.20 kg/m³ and the air dynamic viscosity, µ= 1.80 x 10$ kg/m·s. If the freestream velocity, V = 2 m/s, i. approximate the downstream distance where the thickness of laminar boundary layer, &aminar in meter (m) would be maximum. ii. find the displacement thickness, &* in meter (m) at the downstream location where the boundary layer flow changes from laminar to transitional. iii. someone suggested that the velocity distribution in the laminar boundary layer flow can be expressed as u/V = y/8, where, u is the velocity at a distance, y from the plate, and 8 being the boundary layer thickness, discuss whether the suggested expression is appropriate.
