Question

Bottle was filled with water and a hole is punched in the bottle.When the bottle is closed, water does not come out of the hole. However, when the bottle is open, water comes out of the hole.

Other information would be

- Atmospheric pressure is 1 atm (101325 Pa)

- Assume bottle is 20 cm and the hole is on the 10 cm above the bottom of the bottle (use it as reference level)

Define the pressure(s) acting at the hole when the bottle is open and calculate total pressure.

Define the pressure(s) acting at the hole when the bottle is closed and calculate total pressure.

Using the results from part a and b, why does water come out when the bottle is open and why does not it come out when the bottle is closed?
