1.3. Pipes in Parallel

Try these first

1. 1.

   Define head loss and its significance in fluid flow.

   Hint

   Consider how energy is affected by friction.

2. 2.

   What is discharge, and how is it affected in parallel pipes?

   Hint

   Think about how flow divides among multiple pathways.

3. 3.

   What must be true for the energy losses in parallel pipe systems?

   • They are always zero
   • They must be equal
   • They can be different
   • They are negligible

   Hint

   Think of the flow balance.

4. 4.

   True or False: The discharge in a parallel piping system is divided among the branches.

   • True
   • False

   Hint

   Assess the nature of flow in a system.

5. 5.

   Calculate the total head loss in a two parallel pipe system where pipe A is 3 m long and has a 5 cm diameter with a friction factor of 0.02, and pipe B is 2 m long with a 3 cm diameter and the same friction factor.

   Hint

   Don't forget to square the velocity when calculating for each.

6. 6.

   If two tanks are connected by parallel pipes, with one outlet having higher discharge in one pipe, how can you adjust to ensure a balanced flow at the junction?

   Hint

   Incorporate flow control techniques to achieve balance.
