If you have the pump characteristic curves from your pump supplier and already managed to plot the system resistance curve for the piping system you are designing then it is really very easy to finalize … Read the rest
Refer the concept of the system resistance curve from my previous article for better understanding this article.
You will find an important equation there:
- Total system resistance = Frictional resistance + Resistance due to static head (height difference) + Resistance
Quite often you have to calculate Reynolds number while dealing with hydraulics and pneumatics. Know how to calculate and appreciate its values.
Understanding the following two points will be helpful before going to the actual calculation and formula:
The resistance between two consecutive layers of fluid is viscosity. This resistance is generated because of the fact that different layers flow at different velocity. Or, in other words, there exists some amount of relative velocity which causes … Read the rest
