19.4. Water Supply Systems

Try these first

1. 1.

   What is the primary purpose of a water supply system?

   Hint

   Consider what happens in urban areas with water delivery.

2. 2.

   Define Reynolds number in your own words.

   Hint

   Think of it as a flow behavior indicator.

3. 3.

   What is the typical Reynolds number threshold for laminar flow?

   • 2000
   • 2300
   • 4000

   Hint

   Remember the classification of flow types.

4. 4.

   Is Bernoulli’s equation only applicable to laminar flow?

   • True
   • False

   Hint

   Think about where you have seen this equation applied.

5. 5.

   Consider a water supply system with a main pipe of 100m length, with a diameter of 15cm having a turbulent flow with a velocity of 2 m/s. Calculate the head loss due to friction.

   Hint

   Ensure consistent units for all terms and known values.

6. 6.

   You have an underground pipeline network that needs an elevation of 10m height. Its base has less water flow during dry seasons. How would you adjust your design to accommodate varying demands?

   Hint

   Plan for seasonal variations and adjust design parameters accordingly.
