Answer #1

Option C

Stokes law - Creeping motion

Bluff body - pressure drag

Streamline body - skin friction drag

Karman vortex street - strouhal number

Stokes flow is also known as creeping flow. In this type of fluid flow inertial forces are small compared with viscous forces.

Blunt and bluff body has that causes high pressure drag, because of its shape

Streamline body has low drag force and upto very little hight the velocity of flow is reduced because of friction thus it has skin friction drag

Karman vortex motion is calculated by strouhal number
