21.2.1. Problem Description

Try these first

1. 1.

   What is major head loss attributed to?

   Hint

   Consider the primary cause of energy loss in a streamlined fluid.

2. 2.

   Name one type of minor loss.

   Hint

   Think of pipe fittings that disrupt flow.

3. 3.

   What is the primary cause of major head losses in a fluid system?

   • Friction
   • Temperature
   • Elevation

   Hint

   Recall the factors affecting fluid motion in pipes.

4. 4.

   Minor losses occur from which of the following?

   • True
   • False

   Hint

   Think about how obstacles can disrupt the flow.

5. 5.

   A pipe of length 2000 m with a diameter of 0.1 m carries water. Calculate the major head losses if the friction factor is 0.02. Assume water's velocity is 2 m/s.

   Hint

   Break it down into steps when using the Darcy-Weisbach equation.

6. 6.

   Design a system of pipes that minimizes both major and minor losses while still delivering the required flow rate to a reservoir 50 meters above a lower reservoir. Explain your design considerations.

   Hint

   Think about the geometry of your pipe layout carefully.
