Fluid mechanics

Question 1

Consider three drinking glasses. All three have the same area base, and all three are filled to the same depth with water. Glass A is cylindrical. Glass B is wider at the top than at the bottom, and so holds more water than A. Glass C is narrower at the top than at the bottom, and so holds less water than A. Which glass has the greatest liquid pressure at the bottom?
Glass A
Glass B
Glass C
All three have equal non-zero pressure at the bottom
All three have zero pressure at the bottom

Answer 1

All three have equal non-zero pressure at the bottom

Question 2

Pascal's principle
Bernouilli's principle
Archimedes' principle
Poiseuille's principle

Answer 2

Bernouilli’s principle
