A body is called streamline body when Correct Answer surface of the body coincides with the streamlines

Explanation:

streamlined body:

It is defined as the body whose surface coincides with the streamline when the body is placed in the flow. Flow separation takes place only at the trailing edge in such cases.

  • The boundary layer in such bodies must be attached to the surface of the body for a long time as possible and hence behind a streamlined body wake formation zone will be very small and consequently, pressure drag will be very small.
  • Thus, the total drag on the streamlined body will be due to friction (shear) only.
  • A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. Drag is a force that slows down motion. Friction drag is a special kind of drag.
