1. Basics of fluid mechanics - I (Contd.)

Try these first

1. 1.

   What happens to pressure as you dive deeper into water?

   Hint

   Think about what is above you while underwater.

2. 2.

   What does Pascal's law state?

   Hint

   Consider how pressure is felt in all directions when you squeeze a closed balloon.

3. 3.

   How does pressure change as one goes deeper in a fluid?

   • Increases
   • Decreases
   • Remains constant

   Hint

   Think of how a scuba diver feels more pressure at greater depths.

4. 4.

   True or False: According to Pascal's Law, pressure acts equally in all directions in a static fluid.

   • True
   • False

   Hint

   Consider how pressure is applied uniformly to all parts of a fluid.

5. 5.

   A submarine can operate safely at depths of 500 meters. If the specific weight of seawater is 10 kN/m³, what is the pressure at that depth?

   Hint

   Use the pressure calculation formula based on depth.

6. 6.

   Explain the design changes needed for a dam if the water level behind it increases significantly.

   Hint

   Think about how the force of water on the dam would change as the water height changes.
