6. Applications of Bernoulli's equation

Try these first

1. 1.

   What is Bernoulli’s equation used for?

   Hint

   Think about fluids and their flow behaviors.

2. 2.

   What does HGL stand for in fluid mechanics?

   Hint

   It relates to energy available due to pressure and elevation.

3. 3.

   Bernoulli's equation applies to:

   • Viscous flow
   • Incompressible flow
   • Both

   Hint

   Consider the assumptions behind Bernoulli's principles.

4. 4.

   True or False: The Energy Grade Line is always below the Hydraulic Grade Line.

   • True
   • False

   Hint

   Think about how energy is represented in fluid mechanics.

5. 5.

   A water pipeline with varying diameters shows a pressure drop from 50 kPa to 30 kPa. What are the possible velocity changes if point A's diameter is 10 cm and point B's diameter is 5 cm?

   Hint

   Utilize the relationship between pressure and velocity derived from Bernoulli's principles.

6. 6.

   A pitot tube is used in an airplane flying at a speed of 200 km/h. What static pressure difference is measured, assuming air density is 0.001225 kg/m³?

   Hint

   V is the speed in meters per second, you might want to convert kilometers per hour first.
