9.2. Pressure Measurements

Try these first

1. 1.

   What is a manometer used for?

   Hint

   Think of a device related to height of liquid.

2. 2.

   What is the main principle behind a piezometer?

   Hint

   Focus on liquid columns and their height.

3. 3.

   What principle does a piezometer operate on?

   • Pressure difference
   • Hydrostatic pressure
   • Fluid dynamics

   Hint

   Think about how deep water affects pressure.

4. 4.

   True or False: An inclined manometer is better at measuring high pressures.

   • True
   • False

   Hint

   Consider the design purpose of an inclined manometer.

5. 5.

   A fluid system shows a pressure difference of 60 mm of mercury between two points. If the densities of the fluid and mercury are 900 kg/m³ and 1300 kg/m³, respectively, calculate the height of the fluid column in meters.

   Hint

   Make sure to convert all units to SI before calculating.

6. 6.

   Design a simple experiment using a U-tube manometer to demonstrate pressure differences in different fluid densities. What materials will you use, and what observations will you record?

   Hint

   Consider how the fluids will interact and what measurements you’ll take.
