1.1.1. Velocity Deflect Law

Try these first

1. 1.

   Define velocity defect in fluid flow.

   Hint

   Think about what happens when velocity changes in a turbulent flow.

2. 2.

   What are major losses in fluid systems?

   Hint

   Consider what happens when fluid flows through a surface.

3. 3.

   What does velocity defect represent in fluid dynamics?

   • Difference between instant and average velocity
   • Flow rate
   • Pressure difference

   Hint

   Think about how fluctuations in flow can occur.

4. 4.

   True or False: Energy losses in fluids are only due to friction in pipes.

   • True
   • False

   Hint

   Consider all potential sources of energy loss.

5. 5.

   Calculate the energy loss for a fluid flowing through a pipe of length 100m with a friction factor of 0.02 and a flow rate of 0.05 m³/s.

   Hint

   Make sure to find the corresponding diameter first using the flow rate.

6. 6.

   In a three-reservoir system, if one tank has an elevation of 5m and the others are 2m, calculate the required pressure at the higher tank to maintain flow.

   Hint

   Don't forget to notate each height and how they influence potential energy.
