1.9. Simplification of the pressure expression

Try these first

1. 1.

   What happens to pressure as you go deeper into a liquid?

   Hint

   Think about what is above.

2. 2.

   Define Pascal's Law in simple terms.

   Hint

   Remember: pressure and containers.

3. 3.

   What element affects pressure most significantly in a liquid?

   • Temperature
   • Depth
   • Volume

   Hint

   Consider how weight influences pressure.

4. 4.

   Does pressure only depend on depth in a static fluid?

   • True
   • False

   Hint

   Think about how pressure distributes in still water.

5. 5.

   A submersible vehicle descends to 1000 meters. Calculate the pressure acting on its hull, assuming the density of seawater is 1025 kg/m³. What implications might underestimating this pressure have?

   Hint

   Use the formula for calculating pressure with depth.

6. 6.

   If you had a tank of liquid with height 5 m and opened two valves at different heights, how would the flow velocity through each valve compare?

   Hint

   Think about how pressure relates to depth when determining speed.
