6.2. Pitot tube

Try these first

1. 1.

   What is the main function of a Pitot tube?

   Hint

   Think about where you've seen it used.

2. 2.

   What causes stagnation pressure?

   Hint

   Recall the flow concepts.

3. 3.

   What primary principle does a Pitot tube rely on?

   • Continuity Principle
   • Bernoulli's Principle
   • Pascal's Principle

   Hint

   Consider which principle relates speed and pressure.

4. 4.

   True or False: The flow measured by a Pitot tube can be turbulent without any effect on the readings.

   • True
   • False

   Hint

   Reflect on how flow types affect measurements.

5. 5.

   A small boat has a Pitot tube measuring a static pressure of 80 Pa and a stagnation pressure of 150 Pa. The water density is 1000 kg/m³. Calculate the boat's speed in the water.

   Hint

   Use the density of water for your calculation.

6. 6.

   In a hydraulic system, a Pitot tube measures a pressure difference of 300 Pa, where the liquid density is 850 kg/m³. Determine the velocity of the liquid flow.

   Hint

   Make sure to account for the density in your calculations.
