23.2.1. Applicability to Unsteady Flow

Try these first

1. 1.

   What are streamlines?

   Hint

   Think about how fluid flows through pipes.

2. 2.

   Name one limitation of Bernoulli's equation.

   Hint

   Where would friction be significant?

3. 3.

   What is a streamline?

   • A visible line in fluids
   • An invisible path followed by fluid particles
   • A measure of viscosity

   Hint

   Think of the paths liquids take in a container.

4. 4.

   True or False: Bernoulli's equation can be applied in all flow conditions.

   • True
   • False

   Hint

   Consider scenarios where friction is significant.

5. 5.

   Given a tank with a height of 10 meters and a nozzle area of 0.002 m², calculate the discharge velocity at the outlet, considering that the discharge coefficient is 0.9.

   Hint

   Apply the corrected velocity formula.

6. 6.

   Discuss the practical applications of Bernoulli's principle in engineering and provide two examples where it could be misapplied.

   Hint

   Identify real-world scenarios where assumptions of ideal conditions do not hold.
