Question

Same et Asush The figure shows a uniform pressure, uniform density boundary a that plate. A and B are punts at the. distance from the surface of the plate. Answer and explain how of the following ? for stat plate for pecond along (i) Is the stagnation pressure at A greater than, equal to on Po=Pt is less than that at (B)? (ii) Is the shear stress at (A) greater than equal to, or less than that at (B)? (iii) Does the streamlines passing (A) pass above, through, or below (B) ? Boundary layer edge Voo de (A) (B) سوال

DO EB 2 (dug to so by B Qo Shearshores af B is greater from the Shear Sarness ut A. TBYTA Tacogend and lineam line gives the Melocity of fluid Poistais on the boundary layer edge so its velocity is VAZ Voo (pree scream velocity) point B is with in the boundary layer so ide velocity is less than wo ve NAS NB line passing af A 18 above streem are B
