Experiment 2 — How Far Does the Jet Squirt?

Topic: Physics · Class 8 · Pressure in liquids and the atmosphere

Aim: Make the water jet land at least 40 cm from the bottle.

Daily: A village overhead tank is built high so that taps below have good pressure, deep-sea divers wear pressure suits, and a dam wall is built thick at the bottom where the water pushes hardest.

Question: A tall narrow bottle and a wide jar are filled with water to the same height. The pressure at the bottom is…

Exp: Liquid pressure depends on depth and density, not on the shape or the total amount of liquid.

Question: Pressure in a liquid increases with…

Question: A dam is thicker at the bottom because…

Exp: The base must withstand the highest pressure.

Question: A rubber sucker sticks to a wall because of…

Exp: Air is squeezed out, so outside air pressure holds it.

Exp: Which is why side holes squirt.
