  • When a kink occurs in a pipe during bending, it creates an obstruction in the flow path. This obstruction can lead to increased resistance and turbulence in the fluid flow, resulting in a higher pressure drop.
  • Pressure drop is the loss of pressure as a fluid flows through a pipe or conduit, and it is influenced by factors such as the geometry of the pipe and the smoothness of its interior surfaces.
  • The kink disrupts the smooth flow of fluid, causing turbulence, increased friction, and restrictions. This, in turn, leads to a higher pressure drop as the fluid encounters resistance while passing through the kinked portion of the pipe.
  • Increased pressure drop can have several adverse effects, including reduced efficiency of the fluid system and the potential for damage to pumps and other components due to excessive resistance.
  • Here, option 3 is correct.
