23.3.2. Fluid Flow Analysis Techniques

Try these first

1. 1.

   What is Bernoulli's equation used for?

   Hint

   Think about energy conservation in fluids.

2. 2.

   Define a streamline.

   Hint

   Consider how water flows in a river.

3. 3.

   What is the Bernoulli's equation primarily used for?

   • Predict fluid velocity
   • Calculate temperature changes
   • Estimate density variation

   Hint

   Consider what parts of flow are being analyzed.

4. 4.

   True or False: Friction is negligible when applying Bernoulli's equation.

   • True
   • False

   Hint

   Think back about flow conditions!

5. 5.

   A water tank is 5m high, and water is flowing out from a nozzle at the bottom. Using Bernoulli’s equation, calculate the speed of the exiting water.

   Hint

   Consider the potential energy converting to kinetic energy at the nozzle.

6. 6.

   A pipe narrows from a diameter of 10 cm to 5 cm. Calculate the velocity increase using Bernoulli’s equation assuming no energy loss.

   Hint

   Remember that flow rate must remain constant across the pipe's cross-sections.
