Question

displacement thickness is defined as the​

Answer 1

Answer:

Displacement thickness : It is defined as the distance by which the external potential flow is displaced outwards due to the decrease in velocity in the boundary layer.

Answer 2

Answer:

Displacement thickness : It is defined as the distance by which the external potential flow is displaced outwards due to the decrease in velocity in the boundary layer. Therefore, (29.6) Substituting the values of and from Eqs (28.21a) and (28.19) into Eq.(29.6), we obtain.
