5.2. Real Life Example Problems

Try these first

1. 1.

   What does Bernoulli’s equation relate?

   Hint

   Think about energy in a flowing fluid.

2. 2.

   Define a control volume.

   Hint

   It helps in isolating regions for analysis.

3. 3.

   What does Bernoulli's equation express?

   • Pressure-Temperature Relation
   • Pressure-Velocity-Elevation Relation
   • Velocity-Fluid Density Relation

   Hint

   Think of different forms of energy in fluid dynamics.

4. 4.

   Bernoulli’s principle is applied mainly in which field?

   • True
   • False

   Hint

   Recall its application in real-life scenarios like wind loads.

5. 5.

   A cylindrical tank is filled with water. If there is a hole at a height of 10 m from the bottom, compute the speed of the water jet exiting the hole.

   Hint

   What height does the water drop from?

6. 6.

   In a scenario where wind is uniform across a large area, how would you calculate the total wind load on a building facade?

   Hint

   Make sure to backtrack to Bernoulli's principles.
