# Water Pipe Sizing Calculation Example – Part 1: Overview

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.

Problem Definition

Refer the above schematics (Fig.1) and observe the following inputs:

Total pipe length=7 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

Solution

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.

In the next part (part-2) of this pipe size calculation series will discuss about calculating effective pipe length.
