Lesson 6 – Adding Loops in FHC

One of the most powerful features in FHC is the ability to add loops to your system which can be highly beneficial hydraulically as it allows water to flow in more than one direction. On the most effective uses of loops is in a gridded sprinkler system which allows for relatively small pipes with uniform pipe size and is considered to be highly efficient.

 

So far we have looked on how to ADD new pipe to the system but in the case of the loops we need to link existing node numbers together to form the loop we will still use the ADD pipe command but in this instance we will overwrite end node number with the node pipe you wish to join too.  In this example we are going to join Node 560 to Node 470.

 

 

We need to select the ADD pipe command and then select the Node number 560 so can do this in the same way as adding any other pipe.  Once the ADD pipe dialogue box is open we need to overnight the End node number with the node we wish to connect to in this case 470 to complete the action you must press the TAB key and then the systems will Automatically find the pipe length direction and slope for the pipe to be added. 

 

You will be presented a dialogue box asking you to confirm your acceptance when you press Yes the information will be updated in the add pipe command dialogue box when you press Apply the pipe will be added.

 

After you press the apply button the drawing be updated to include the pipe which is now forming a loop in the system. 

 

 

As you add loops to the system the loop counter will be updated to show the current count of all the loops in the system in this case one loop L:1

 

Will need to repeat the above process to form each loop in the system in a further example we will have to add an additional three pipes.  The recommended process when you have a project with loops or grids is that you draw as much as the pipework as possible but without forming the loops then save this project as a master template.  Now start to add the loops as you require for your project checking that the loop counter the status bar is incremented by one each time you add a loop.

This short video we show you the steps required at the pipes the form four loops in the above example.
