21.3.1. Problem Overview

Try these first

1. 1.

   What is a major head loss?

   Hint

   Think about flow resistance in pipes.

2. 2.

   What contributes to minor head losses?

   Hint

   Look for components affecting flow direction.

3. 3.

   What does major head loss primarily relate to?

   • A) Bends
   • B) Friction
   • C) Valves

   Hint

   Think about what happens inside smooth vs rough pipes.

4. 4.

   True or False: Minor losses have a negligible effect on overall head loss.

   • True
   • False

   Hint

   Consider their cumulative impact in complex systems.

5. 5.

   Given a pipe with a length of 500 meters, a diameter of 0.25 meters, and a friction factor of 0.03, compute the major head loss using the Darcy-Weisbach equation.

   Hint

   Calculate velocity by continuity or given flow rate.

6. 6.

   In a piping system with two bends and a valve, calculate the total head loss when bend losses are 1.5 m head loss each and the valve's loss coefficient indicates a 2 m loss.

   Hint

   Add all losses together for the total head loss.
