Question

Explain how drinking through a straw illustrates fluid flowing from high-pressure to low-pressure areas.

Answer 1

The outside pressure forces the liquid up the straw and into your mouth. So, just by drinking through a straw, you can observe an important property of fluids. Fluids flow from areas of high pressure to areas of low pressure.

Answer 2

the pressure in the straw is reduced, but the atmospeheric pressure on the surface of the liquid stays the same.
