Fluid properites

Question 1

what is cavitation and how can it occur?

Answer 1

areas of low pressure occuring locally in a flowing liquid. If it falls below vapour pressure, there will be local boiling and bubbles will form.

Question 2

what is the equation to find force on a solid in a static fluid due to the fluid?

Answer 2

specific weight * volume (you have to add atmospheric pressure to find total pressure)

Question 3

whats the relationship between pressure and depth of an object in a fluid

Answer 3

directly proportional (can be proven by differentiation)
