Loops 1.02

Program Description

LOOPS - Hardy Cross Pipe Analysis

Implementation of the familiar Hardy-Cross pipe distribution algorithm. This software was designed for classroom use in hydraulics. It allows students to analyze pipe distribution networks. Support for Darcy-Weisbach and Hazen Williams friction methods is offered. On-line documentation includes all example problems needed to get up and running in the classroom with this software. If you have previous installed the LOOPS program and wish to update the executable only the current version of the executable only can be downloaded by clicking on the update below. It must be unzipped into the LOOPS directory.

Loops 1.02 is a program which allows users to perform Hardy Cross method hydraulic loop analysis. Performing this analysis involves a number of steps. These steps should be followed for a successful Hardy Cross analysis of your network.

 1. Lay out your network on Paper

 2. Assign Numbers and Flow Directions

 3. Enter Data in Loops

 4. Check All Data

 5. Calculate All Parameters in Loops

 6. Output Data

The Hardy Cross Method

By following this procedure you can perform the Hardy Cross analysis by hand. With the exception of assuming flow directions, the computer program will perform this entire procedure. Note that the procedure must be carried out on all loops and the the correction factor applies to each loop. Most basic hydraulics texts contain detailed discussions of this procedure.
