19.5.1. Major and Minor Losses in Pipes

Try these first

1. 1.

   Define major losses in pipe flow.

   Hint

   Consider friction as a type of energy loss.

2. 2.

   What is the definition of minor losses?

   Hint

   Think about how fittings affect flow.

3. 3.

   What are major losses primarily due to?

   • A) Fittings
   • B) Friction
   • C) Expansion

   Hint

   Think about what happens when fluid flows through a surface.

4. 4.

   True or False: Minor losses only occur when the pipe diameter increases.

   • True
   • False

   Hint

   Consider the effects of bends and valves.

5. 5.

   A pipe with a diameter of 0.5 m and a length of 100 m has a friction factor of 0.01. Determine the major head loss when the flow velocity is 5 m/s.

   Hint

   Include gravitational acceleration in your calculations.

6. 6.

   What is the cumulative head loss in a system with three bends, each having a K-value of 0.3, and a flow velocity of 4 m/s?

   Hint

   Don't forget to use consistent units throughout your calculations.
