6.1. Stagnation tube

Try these first

1. 1.

   What is a stagnation tube used for?

   Hint

   Think about how fluids can be at rest.

2. 2.

   Name one application of Bernoulli's equation.

   Hint

   Consider how speed and pressure relate.

3. 3.

   What does a stagnation tube measure?

   • Temperature
   • Static Pressure
   • Velocity

   Hint

   Think about the position of the fluid in the pipe.

4. 4.

   True or False: Bernoulli's equation is valid across different streamlines.

   • True
   • False

   Hint

   Consider what happens when you cross streamlines.

5. 5.

   A pitot tube reading shows a difference of 200 Pa between stagnation and static pressure. Calculate the flow velocity in the duct.

   Hint

   Remember to use the density of the fluid.

6. 6.

   Discuss how real-world factors like turbulence and viscosity can influence the results derived from Bernoulli's equation in practical applications.

   Hint

   Think about how flow changes with different velocities and with friction.
