6.2.3. Linear Momentum Equations for Control Volume

Try these first

1. 1.

   Define a control volume in fluid mechanics.

   Hint

   Think of it as a box around a flowing fluid.

2. 2.

   What does Reynolds Transport Theorem connect?

   Hint

   Look for relationships between systems and their boundaries.

3. 3.

   What is momentum in fluid dynamics?

   • Mass divided by velocity
   • Mass times velocity
   • Mass plus velocity

   Hint

   Think about the physics definition involving motion.

4. 4.

   True or False: Bernoulli's equation only applies to incompressible fluids.

   • True
   • False

   Hint

   Focus on the properties of the liquids being analyzed.

5. 5.

   Calculate the forces acting on a jet of water flowing at a rate of 20 liters per second striking a vertical wall. Use Bernoulli's equation for pressure to determine impact force.

   Hint

   Remember to express flow rate in terms of cubic meters per second.

6. 6.

   Derive the relationship between pressure drop and fluid velocity for a venturimeter with known inlet and outlet diameters, and ensure consistency in your energy equations.

   Hint

   Follow the ACE formula: Area, Continuity, Equation to derive the values.
