9.1.1. Measurement of Pressure and Hydrostatic Forces

Try these first

1. 1.

   What is hydrostatic pressure?

   Hint

   Think about how the fluid behaves when it's not moving.

2. 2.

   Name a type of manometer.

   Hint

   Think of a 'U' shape!

3. 3.

   What does hydrostatic pressure depend upon?

   • Weight of the fluid
   • Temperature of the fluid
   • Depth of the fluid

   Hint

   Consider what happens as you go deeper into a pool.

4. 4.

   True or False: An inclined manometer can measure low pressures more effectively than a vertical manometer.

   Hint

   Think about how angles might enhance performance.

5. 5.

   A U-tube manometer connected to a gas pipeline shows a height difference of 3 cm between the two arms. If the density of the manometric fluid is 850 kg/m³, calculate the gauge pressure in the pipeline (g = 9.81 m/s²).

   Hint

   Use the manometer height and fluid density to calculate pressure difference.

6. 6.

   Design a stepped well that allows access to water during drought. Describe how hydrostatic principles guide your design choices.

   Hint

   Consider how depth influences ease of access.
