21.3.2. Given Data

Try these first

1. 1.

   What is head loss?

   Hint

   Think about energy loss in terms of friction.

2. 2.

   Name the types of losses in pipes.

   Hint

   Consider friction as a factor.

3. 3.

   What is the primary cause of major head losses in pipes?

   • A) Bends and Valves
   • B) Friction in Pipe Material
   • C) Water Temperature

   Hint

   Think about the material properties.

4. 4.

   True or False: Minor losses are only caused by bends in pipes.

   • True
   • False

   Hint

   Consider other interruptions in flow.

5. 5.

   A water pipe with a diameter of 0.15 m runs 1500 m at a friction factor of 0.025. Calculate the head loss if the average velocity is 2 m/s.

   Hint

   Ensure each variable is properly substituted.

6. 6.

   You have two reservoirs with a head difference of 45 m. A pipe connects them, and it includes a valve with a loss coefficient of 2. Calculate total head loss considering friction and the valve.

   Hint

   Keep your units consistent and check your loss equations.
