3.3. Application along a streamline

Try these first

1. 1.

   Define Bernoulli's equation in your own words.

   Hint

   Think about the relationship between pressure and velocity.

2. 2.

   What does HGL stand for?

   Hint

   Remember the significance of pressure head in a fluid system.

3. 3.

   What does Bernoulli's equation express?

   • Relationship of velocity and temperature
   • Conservation of mechanical energy in fluids
   • Pressure in static fluids

   Hint

   Think about the energies present when a fluid is in motion.

4. 4.

   Does Bernoulli's equation work for compressible fluids?

   • True
   • False

   Hint

   Recall the assumptions made during the derivation.

5. 5.

   A fluid flows from a large diameter pipe to a smaller one, causing a pressure drop of 15 kPa. Determine the velocity increase if the flow rate remains constant.

   Hint

   Keep in mind the relationship between area and velocity in pipes.

6. 6.

   A pitot tube shows a stagnation pressure of 50 kPa while static pressure is 30 kPa. Calculate the fluid's velocity.

   Hint

   Remember how to rearrange Bernoulli's equation to isolate velocity.
