Question Statement:
Figures (a) - (d) below show four objects. Dimensions and surface conditions of the objects are
shown in the respective figures. All four objects are placed independently in a steady, uniform flow
of same velocity and the direction of flow is from left to right as shown in (a). The flow field can be
considered as 2-D, viscous and incompressible. Following statements are made regarding the drag
that these objects experience.
(i) Drag of object (a) is more than the drag of object (d)
(ii) Drag of object (a) is less than the drag of object (d)
(iii) Drag of object (b) is more than the drag of object (c)
(iv) Drag of object (c) is more than the drag of object (b)
(v) Drag of object (a) is more than the drag of object (b)
Choose the correct combination of statements from the options given above:
(A) (i), (iii), (v) (B) (ii), (iv), (v) (C) (i), (iv), (v) (D) (i), (iii)
