Streamlining

The lines of laminar flow are called streamlines. At any point, the velocity is constant over time.At any point the water will always move at the same speed in the same direction. In different places the speed and direction will be different.Streamlining provides very little resistance to the flow of air or water, increasing the speed and ease of movement through a fluid.Engineers can reduce a vehicle's fuel consumption by reducing its size and weight and by streamlining its body.
