7.3. Hydrostatics

Try these first

1. 1.

   What is hydrostatics?

   Hint

   Focus on the state of fluids.

2. 2.

   State Pascal's Law.

   Hint

   Think about pressure in closed containers.

3. 3.

   What is Pascal's law?

   • Pressure is transmitted equally in all directions in a fluid at rest.
   • Pressure decreases with depth in a fluid.
   • Only pressure from below affects a fluid's surface.

   Hint

   Think about how pressure changes in a fluid.

4. 4.

   True or False: Gauge pressure includes atmospheric pressure.

   • True
   • False

   Hint

   Remember the difference between gauge and absolute pressure.

5. 5.

   A rectangular tank is filled with water 5 meters deep. Calculate the hydrostatic pressure at the bottom of the tank. Assume water density is 1000 kg/m³.

   Hint

   Remember to include the unit conversions where needed.

6. 6.

   Explain the significance of capillary action in plants using hydrostatic concepts.

   Hint

   Think about how small diameter tubes can bring liquids upwards.
