Fluid Dynamics and Measurement Techniques Quiz

What is the principle behind a manometer used to measure pressure?

• The pressure of a fluid is directly proportional to its velocity.

• The pressure difference between two points in a fluid is proportional to the height difference of the fluid column in the manometer.

• The pressure of a fluid is inversely proportional to its temperature.

• The pressure of a fluid is determined by its density alone.
