20.2.1. Velocity Distributions

Try these first

1. 1.

   Define laminar flow.

   Hint

   Think about how a river flows smoothly.

2. 2.

   What is head loss?

   Hint

   Consider what happens when there is resistance in a pipe.

3. 3.

   What characterizes laminar flow?

   • Chaotic and mixed
   • Smooth and layered
   • Fast and turbulent

   Hint

   Think of how calm water flows.

4. 4.

   True or False: Head loss is always a negative factor in fluid flow systems.

   • True
   • False

   Hint

   Consider the implications of energy loss.

5. 5.

   A fluid flows through a pipe with a diameter that gradually increases. Calculate the change in velocity as it passes from a smaller to a larger diameter area, given the initial velocity and dimensions.

   Hint

   Make sure to calculate the cross-sectional areas first.

6. 6.

   You have a globe valve that causes a head loss of 5 meters in a fluid flow system. Calculate the power loss due to this head loss considering the flow rate.

   Hint

   Be mindful of units and conversions.
