If a thin plate is held parallel to fluid stream the pressure drag on it is:
Bluff body is the body of such a shape that pressure drag as compared to friction drag is
Boundary layer is defined as
A body is called streamline body when
Separation of flow occurs when pressure gradient:
Separation of flow occurs when pressure gradient
The nominal thickness of the boundary layer is defined when the velocity reaches the velocity of the free stream by
Separation of boundary layer takes place when
Boundary layer thickness is the distance from the boundary to the point where the velocity of the fluid is
In the region of boundary layer on a flat plate surface where velocity is not zero, the viscous force is
Under what condition does flow separation take place?
Within the boundary layer region, which force dominates over inertia force?
A streamlined body is one for which:
Which one of the following is not the methodology of control separation of flow from boundary in the application of aerofoils ? 
The boundary layer exists in which of the following ?
