22.5.2. Pressure Distribution

Try these first

1. 1.

   What is Bernoulli's equation primarily about?

   Hint

   Think about how these variables interact in a fluid system.

2. 2.

   Define incompressible flow.

   Hint

   Consider liquids in motion.

3. 3.

   What does Bernoulli's equation relate to?

   • Pressure
   • velocity
   • and temperature
   • Pressure
   • velocity
   • and elevation
   • Velocity
   • speed
   • and friction

   Hint

   Remember the primary variables that appear in the equation.

4. 4.

   True or False: Bernoulli's equation is applicable to all fluid flows.

   • True
   • False

   Hint

   Think about the assumptions that govern its use.

5. 5.

   Explain how Bernoulli's equation can be used to determine the speed of a fluid flowing through a horizontal pipe with varying diameters.

   Hint

   Focus on the relationship between pressure and velocity as diameter changes.

6. 6.

   Provide an analysis of how the lift on an airplane wing can be affected by changes in airspeed and angle of attack.

   Hint

   Consider how the balance between pressure differences above and below the wing is key.
