Question

Consider the following statements about fluid flow (True, False, Greater than, Less than, or Equal to):

1. Bernoulli's equation assumes that the fluid is incompressible.

2. If the radius of a water pipe becomes twice as large the flow speed of a non viscous fluid will be .... one fourth of its initial value.

3. Bernoulli's equation applies to viscous fluids.

4. Streamlines do not cross each other.

5. As fluid flows through a horizontal pipe the pressure at a narrow point is ... the pressure where the pipe is wider.

6. Bernoulli's equation describes the energy loss along a streamline.

Thanks so much!!

Explanation / Answer

1. pressure is lower when velocity is higher
2. streamlines don't cross by definition
3. true
4. its conservation of energy, but that could mean it describes energy loss by saying it isn't lost...
5. true
6. false
