23.4.1. Finding Relationships in Fluid Flow

Try these first

1. 1.

   What is Bernoulli's equation primarily used for?

   Hint

   Consider the relationship between pressure and velocity.

2. 2.

   Name one assumption made when applying Bernoulli's equation.

   Hint

   Think about the ideal conditions for flow.

3. 3.

   What is one key assumption when applying Bernoulli's equation?

   • Frictionless flow
   • Compressible flow
   • Unsteady flow

   Hint

   Recall the basic conditions for applying the equation.

4. 4.

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

   • True
   • False

   Hint

   Think about when the assumptions of the equation may fail.

5. 5.

   A horizontal pipe carries water at a pressure of 200 kPa. If the diameter at the first point is 10 cm and at the second point is 5 cm, calculate the velocity at both sections using Bernoulli's equation.

   Hint

   Remember that the pressure readings will allow you to compute the velocities at both sections.

6. 6.

   You're tasked with designing a nozzle with a discharge coefficient of 0.85. Calculate the expected outflow velocity given an inlet height of 4m.

   Hint

   Be sure to include the discharge coefficient in your calculations for the real scenario.
