Web84K views 2 years ago I cover four types of friction. Static, fluid, kinetic, and rolling. Static friction in which two surfaces are not moving past each other. Sliding or Kinetic friction... WebDec 14, 2024 · In a frictionless flow stream, fluid pressure decreases as fluid velocity increases in order to conserve energy. Another way to think of this is that a pressure differential must develop in order to provide the “push” needed to accelerate the fluid from a low speed to a high speed.
