19.. Fluid Mechanics

Try these first

1. 1.

   What is the relationship between inertia and viscous forces in fluid flow?

   Hint

   Think about fluid movement types.

2. 2.

   At what Reynolds number do we observe turbulent flow?

   Hint

   Recall the threshold numbers discussed.

3. 3.

   What is a key indicator of turbulent flow?

   • Re < 2300
   • Re > 4000
   • Re = 2000

   Hint

   Remember the flow categories discussed.

4. 4.

   Bernoulli’s equation is applicable to which type of flow?

   • True
   • False

   Hint

   Recall the principles behind energy conservation in fluids.

5. 5.

   A horizontal pipe with a diameter of 0.1 m has a fluid flowing at a velocity of 2 m/s. Calculate the Reynolds number, and state whether the flow is laminar or turbulent.

   Hint

   Focus on determining whether the flow exceeds the turbulent threshold.

6. 6.

   Water flows through a series of pipes with varying diameters, analyze how energy loss differs between a wide and narrow pipe setup using calculus-based integration of velocity profiles.

   Hint

   Think about how fluid behavior changes as pipe dimensions vary.
