9.2.5. Micro Manometers

Try these first

1. 1.

   What is a piezometer?

   Hint

   Think of how we measure water levels.

2. 2.

   Describe the main purpose of a micro manometer.

   Hint

   What smaller pressures would be important in industry?

3. 3.

   What is the primary function of a U-tube manometer?

   • To measure temperature
   • To measure pressure differences
   • To measure flow rate

   Hint

   Remember what type of force it reflects.

4. 4.

   Is a micro manometer used for measuring small or large pressure differences?

   • True
   • False

   Hint

   Consider their application in industrial contexts.

5. 5.

   A U-tube manometer is used to measure a pressure difference between two water pipes. The left column is 10 cm tall, and the right column is 4 cm tall. Calculate the pressure difference in Pascals if the density of water is 1000 kg/m³.

   Hint

   Use the difference in heights and remember the formula.

6. 6.

   Design an inclined manometer for a situation where low pressure measurement is critical. Describe its components and how it enhances measurement accuracy.

   Hint

   Think about how angle impacts the scale used.
