2.1. Given Data and Initial Calculations

Try these first

1. 1.

   What is the definition of laminar flow?

   Hint

   Think about how the layers of fluid move.

2. 2.

   What is the unit of measurement for discharge?

   Hint

   Consider what volume and time represent.

3. 3.

   What defines laminar flow?

   • Layered flow
   • Chaotic flow
   • High turbulence

   Hint

   Think about how fluid layers behave.

4. 4.

   True or False: Reynolds number indicates the type of flow—laminar or turbulent.

   • True
   • False

   Hint

   Consider its role in fluid mechanics.

5. 5.

   A water pipe has a diameter of 0.1 m and viscosity of 0.001 Pa.s. If it carries 0.02 m³/s, calculate the Reynolds number.

   Hint

   Substitute density, velocity, diameter, and viscosity into the formula.

6. 6.

   Determine the pressure difference for oil with viscosity 0.9 Poise and specific gravity 0.8 flowing through a 15 m long pipe with a diameter of 0.08 m, offering a discharge of 0.003 m³/s.

   Hint

   Convert viscosity from poise to Pa.s if needed and calculate step by step.
