9.1.4. Differential Manometer

Try these first

1. 1.

   What type of manometer measures the pressure difference between two points?

   Hint

   Look for the type that involves comparing pressures, not just measuring one.

2. 2.

   What does hydrostatic pressure depend upon?

   Hint

   Consider what influences how high water can be pushed in a column.

3. 3.

   What type of pressure does a differential manometer measure?

   • Absolute Pressure
   • Gauge Pressure
   • Differential Pressure

   Hint

   Think about the term differential.

4. 4.

   True or False: Piezometers are used to measure pressure differences.

   • True
   • False

   Hint

   Piezometers only give one value!

5. 5.

   In a pipeline, two points A and B are connected to a differential manometer reading a height difference of 10 cm. The density of the manometric fluid is 800 kg/m³. Calculate the pressure difference between points A and B.

   Hint

   Convert cm to meters and use the acceleration due to gravity.

6. 6.

   A mercury manometer shows a height difference of 15 cm between two points in a pipe, with the density of mercury being 13,600 kg/m³. What is the pressure difference?

   Hint

   Remember to use the right density for mercury while calculating.
