19.4.2. Importance of Energy Losses in Systems

Try these first

1. 1.

   What are major losses in fluid systems?

   Hint

   Think about what affects the flow through pipes.

2. 2.

   Define minor losses.

   Hint

   Consider components that disrupt flow.

3. 3.

   What defines major losses in piping systems?

   • Friction in the pipe
   • Fittings and bends
   • Elevation changes

   Hint

   Think about what happens as fluid moves through a straight pipe.

4. 4.

   Is the Reynolds number more than 4000 indicative of laminar flow?

   • True
   • False

   Hint

   Recall the thresholds for flow types.

5. 5.

   Given a specific water supply system, calculate the major and minor losses. Assume flow rates and identify the components contributing to losses.

   Hint

   Remember to consider all points of entry and exit for the water flow.

6. 6.

   How would the energy loss in a piping system change if we increase the pipe diameter vs. if we increase turbulence?

   Hint

   Think about how wider paths decrease obstacles for moving fluids.
