Velocity distribution in the boundary layer is given sin (17) where u is the velocity at 28 by U₁ vertical coordinate y, U is the free stream velocity

The streamline passing through the distance '8' from the surface at the trailing edge passes through distance 'y' at the leading edge as y shown in figure below. The ratio is (Assume linear profile inside the boundary layer). Streamline U y 10

SITUATION: A steel tape with coefficient of linear expansion of 0.0000116 per °C is known to be 50 m long at 20°C. The tape was used to measure a line which was found to be 532.28 m long and when the temperature was 35°C. Zoom image Find the correct length of the line. O532.62 532.29 532.86 532.37

01: Consider laminar flow over a flat plate. The boundary layer thickness o grows with distance x down the plate and is also a function of free-stream velocity U, fluid viscosity u, and fluid density p. Find the dimensionless parameters for this problem, being sure to rearrange if neessary to agree with the standard dimensionless groups in fluid mechanics. Answer: %3D
