Pipe Properties The new Pipe Properties replaces the View details on a pipe and provides considerably more

flexibility allowing you to see the pipe properties at anytime. You can activate the Pipe properties

window from the Menu View -> Pipe Properties or you can use the [Ctrl + V] short cut. Once the

Pipe Properties winnow is open you can select pipes on the screen with the mouse as required.

You can also use other commands and the pipe properties will remain in view. You can close the

window by using the menu command or the [Ctrl + V] sort cut.

You can also see an extended list of properties by double clicking on the pipe properties window

and return to the normal window by a single mouse click.

Tools -> Options Delete backup files will now delete all BAK and FH! in the current project folder.

Empty TMP folder this command will delete all the files in the TMP folder (c:\fhc\tmp) and should

be used occasionally as a good

housekeeping.

Reset stored lists allows the use to reset

lists which are used in the Project Data

window.

Reset Defaults this will reset a number of

FHC deflates settings such as window

locations and





Project Date Options A number of Project options have now been made more assessable and can be accessed from the

Project Data [Ctrl + P] -> Design Area tab, Options button.

Pressure loss equation You can now easily switch between Hazen-Williams and Darcy-Weisbach pressure loss equation and

back by using the DWF button on the Project Data [Ctrl + P]





FHC Test verification module The new test verification module can be used to verify that the FHC calculation engine is producing

the correct resolute by running a number of predefined calculation testing many variables. Once

the calculations are complete the results are displayed as bellow and by pressing the Print button

you can produce a printed record on paper or to PDF.

The report (as bellow) will be useful evidence to retain for quality assurance purposes and proof of

calibration. The report also includes the users name and the computers ID.





Save after caculation

If you select a sub set of heads and make a calculation FHC will not ask you if you wish to save the sub set as it did before. If you wish to save the selected heads in to a new project file then you need to select the Part save check box before you press the OK button.

Error Handaling You can now switch off all error checking reporting by pressing the OFF, ON button which is located on the right of the status bar. If errors are found the number of errors will be repoted on status bar and a summary of errors is dispayed in the cacluation summary.

Minor Changes

The Load Heads command on the Project Data -> Head Codes now correctly refreshes

The Quick Grid wizard now save the FHC project in: My Documents -> My FHC -> Projects -> Quick Grid

Head data report: if the project had more than 1500 pipes the report would give an error message but the report screen was correct.

Added addition tool tips to the Project Data Form [Ctrl + P]

Added support of vary large screen resolutions and improved two screen handling. Added addition tool tips to the Project Data Form [Ctrl + P]

Comment box added to the bottom of the Calculation Dialog window.

Added additional help files and release notes to the Help menu.





FHC Version 1.6.0 If you open a FHC project file and go to the Project Data [Ctrl+P] Head Codes you will see that a

number of your options have been added Compact, Save and Load the following is a short

description of each:

Compact This will inspect the FHC project file and remove any unused head codes it will also

renumber the remaining head codes starting at 1.

Save With the save command you can create your own head code library files to use with

any other project. The command will save the head codes in the current FHC project

file to an external file which will be stored in the Library folder. You can name the

file anything you like but if you overwrite the user.hcl file then this will be used for

any new projects which you create.

Load This command will allow you to read in an existing Head Code Library File which

has been created with the Save Command above. The head codes loaded will be

added to the existing head codes in the FHC project.

Reports We have simplified the creation for PDFs for all of the reports available on the Reports menu.

When you open the report and see the preview screen select the Print to file checkbox and you

should see two additional dropdown boxes as

shown bellow.

The first drop down box cannot be changed and

the second box gives the location to store the

PDF. By default FHC will store the PDF in the

folder in which you saved the FHC project and

will use the following file name: FR-.pdf.





If you wish you can specify the location and name of the PDF file by selecting the down arrow on

the dropdown box.

The above method works with the Calculation, Head and Pipe reports with the following prefix

been amended to the FHC project file name

FR-.pdf : Calculation report

HR-.pdf : Head summary report

PR-.pdf : Pipe summary report

DXF File When you use the Reports-> Export to DXF function FHC will now save the DXF file in the same

folder in which the project was saved in. The file name will be the same as the project file but with

the DXF file extension.

Save Picture The save picture command Reports -> Save picture will now save the BMP image file in the same

folder in which the project was saved in. The file name will be the same as the project file but with

the BMP file extension.

Calculation Summary Design Efficiency has been added the Calculation Summary. This calculates the overall design

efficiency of the system and is based on the total minimum flow required for the system for each

head to achieve the minimum design density or minimum operation pressure. This theoretical flow

rate is divided by the calculated source flow and the answer is expressed as a percentage. If the

theoretical flow for the system is 1500 L/min and the calculated source flow is 1800 L/min then the

Design Efficiency would be (1500/1800) * 100 = 83%.

Pipe Summary Report We have added the total pressure drop and the static for each pipe in the network. Please

remember that you can sort by any column by selecting the column header.

Pipe Data Table The STD_PIPE.PDT has been amended and now includes considerabl more pipe sizes than before

Hcalc Hcalc is a simple hydraulic calculator which is a

replacement for the existing tool in FHC. However this

tool has a number of enhancements including that it can

be run as a standalone program without FHC. The

program is available from FHC menu Tools -> Hcalc or

from a short cut on your desktop.
