This water piping system design calculation example will use the Darcy-Weisbach equation to calculate the pressure loss in a pipe and using that value it will check the appropriateness of the assumed pipe size.
Refer the above schematics (Fig.1) and observe the following inputs:
Total pipe length=7 meters
Pressure head=5 meters
Number of ball valves=2
Number of Tee bend=1
Also assume that the required flow rate at the pipe end is 0.5 liter/sec.
Find out the appropriate pipe size
Following stepwise procedure needs to be followed for finding out the appropriate pipe size of this water pipe sizing calculation example:
Step-1: Assume the pipe diameter as 20 mm.
Step-6: Determine the Reynolds Number
In the next part (part-2) of this pipe size calculation series will discuss about calculating effective pipe length.
