18.1.5. Conservation of Momentum

Try these first

1. 1.

   Define momentum in your own words.

   Hint

   Think about how mass and speed work together.

2. 2.

   What is a control volume?

   Hint

   It's the area we focus our calculations on.

3. 3.

   What principle describes the conservation of momentum?

   • Mass remains constant
   • Momentum is constant in a closed system
   • Energy is conserved

   Hint

   Focus on the system's isolation.

4. 4.

   True or False: The Reynolds transport theorem only applies to steady flows.

   • True
   • False

   Hint

   Consider all flow conditions.

5. 5.

   A fluid flows in a pipe into a tank with varying diameters. Given different velocities at each section, calculate the overall momentum entering the tank.

   Hint

   Remember to factor in the cross-sectional area at each diameter.

6. 6.

   In a system with turbulent flow, the density varies significantly. Apply the momentum flux correction factor to find the accurate momentum transfer.

   Hint

   Adjust calculations based on observed flow patterns.
