Question

1. Explain the relationship between the area of a tube and fluid’s velocity.
2. If a pipe with flowing water has a cross-sectional area nine times greater
at point 2 than at point 1, what would be the relation of flow speed at the
two points?
3. Blood travels through an artery at velocity v. If a vasoconstriction chemical
is consumed and the artery constricts to half the original diameter, what
is the new velocity of the blood?
4. Explain Bernoulli’s principle. Give an example how this principle is being
applied or observed in our daily lives
