20.5.1. Experimental Data Overview

Try these first

1. 1.

   Define mass conservation in the context of fluid dynamics.

   Hint

   Think about how mass can change in a closed system.

2. 2.

   What is Bernoulli’s equation used for?

   Hint

   Consider what happens to energy in a flowing fluid.

3. 3.

   What is the main principle behind mass conservation?

   • Mass can change
   • Mass remains constant
   • Mass is lost

   Hint

   Think about how mass behaves in different systems.

4. 4.

   True or False: Bernoulli’s Equation only applies to turbulent flow.

   • True
   • False

   Hint

   Recall what Bernoulli's Equation states.

5. 5.

   You have a pipe with a diameter of 0.1 m narrowing to 0.05 m. If the flow rate is 300 L/min, calculate the velocities at both points and determine if the flow is laminar or turbulent based on the Reynolds number.

   Hint

   Convert L/min to cubic meters per second for calculations.

6. 6.

   A system has a globe valve causing a head loss of 5 m and a gate valve causing a head loss of 12 m for the same flow conditions. Analyze the implications of using these valves in system design.

   Hint

   Consider how energy losses affect system efficiency over time.
