Consider air flows with velocity of U?=U=10 m/s over a semi-finite smooth flat plate with L=97 cm long. Calculate the followings by assuming ? = 1.568 x 10-5 m2/s and ?=1.177 kg/m3.
b) Under some flow and boundary conditions (e.g. low-turbulent-intensity free-stream) the transition to turbulence could significantly be delayed. Assume that the laminar flow starting from x = 0 and covers the whole length of the plate (i.e. no transition to turbulence occurs whithin the length of the plate). Calculate the boundary layer thickness (the value ?) at the end of the plate under :
?laminar :
c) up to wich point will the flow be laminar and what wil be the boundary layer thickness at this point?
