Q

what is turbulent flow

A

it is when the velocity of a fluid in a particular place would change over time, often in unpredictable manners

Q

the velocity at which the laminar flow changes to the turbulent flow depends on what factors

A
  1. the fluid itself

2. the area of the shape the fluid is going throw

Q

what are streamlines

A

they are lines of laminar flow in which velocity is constant over time (same direction, same speed)

Q

what are the disadvantages of having a car with poorly designed with a turbulent flow

A

more friction on the car so travels and lower speeds, and more fuel consumption
