21.3.3. Total Head Loss Calculations

Try these first

1. 1.

   What is the formula to calculate major head loss?

   Hint

   Think about the factors that influence friction.

2. 2.

   Define minor head loss.

   Hint

   Consider what happens at each connection in a pipeline.

3. 3.

   What is the Darcy-Weisbach equation used for?

   • To calculate minor losses
   • To calculate major losses
   • To calculate overall efficiency

   Hint

   Think about what losses the equation accounts for.

4. 4.

   True or False: Minor head losses are primarily due to friction.

   • True
   • False

   Hint

   Differentiate between the types of losses.

5. 5.

   A 1 km long pipe flows water at 1 m/s with a friction factor of 0.02. Calculate the head loss and determine the pressure drop using technology principles.

   Hint

   Make sure to convert all units consistently.

6. 6.

   Evaluate a system with multiple branches: one with a K value of 2.0, another valve with K=1.2 and friction factor of 0.025. How will you compute total head loss?

   Hint

   Apply the formulas learned and ensure all K values are incorporated.
