3. Control valve allowable dP range can cause erroneous Cv results (PB 002-11)
   Background PIPE-FLO’s “Allowable dP Range” feature is used to specify a range of differential pressure values as an operational requirement. If the differential pressure calculated for the valve is outside of the specified range a warning is issued to the user. This should no ...
4. PUMP-FLO/PIPE-FLO Curve Information box Issue *missing tabs/scroll bar*
   If the tabs or scroll bar appear to be missing in your Pump Curve box, changing the DPI Settings to 96 DPI or normal fonts will correct the problem you are experiencing. WINDOWS XP: 1. Click on Start then Control Panel. 2. If control panel is set at Classic View, then double-click on the Di ...
5. Program Crashes when printing BOM with multi-stage catalog pump (PB 001-11)
   Background Printing a bill of materials (BOM) report will cause the program to crash if the system has a multi-stage catalog pump with a “Line” field. The multi-stage pump must be from one of Engineered Software’s electronic pump manufacturer catalogs. The multi-stage pumps re ...
6. Flow demands with multiple fluid zone densities (PB 003-10)
   Background Mass flow rates are used for the system network balance in the program. When a flow rate is specified in standard or volumetric flow units, it is converted to a mass flow rate and then fed into the calculation engine. Likewise, once the calculations are completed the results are co ...
7. Standard flow rate calculations for custom fluids (PB 002-10)
   Background Mass flow rates are used for the system network balance in the program. When a flow rate is specified in standard flow units, it is converted to a mass flow rate and then fed into the calculation engine. Likewise, once the calculations are completed the results are converted from th ...
8. Manually entered pump curve data is being incorrectly reset (PB #001_10)
   Background Issues with user-entered pump curves in PIPE-FLO 2009 and Flow of Fluids Premium 2009 have been identified. The increments for trimming the impeller may be limited and the pump curve data may be reset to the design curve or maximum curve when it is not intended by the user. Also, the ...
9. The PIPE-FLO Compressible 2005 Tutorial is missing the file Compressible Tutorial.cdes
   When PIPE-FLO Compressible 2005 is installed from the Evaluation CD, the design file "Compressible Tutorial.cdes" referenced by the tutorial is not installed in the "My Documents\My Engineering Files\Designs" folder. The third page of the PIPE-FLO Compressible 2005 Tutorial references the file " ...
10. Tutorial Browse Sequence
    Some users have experienced problems when trying to run the PIPE-FLO Professional tutorial. The browse sequence interface does not work correctly. The cause of this problem has been traced to an incorrect version of the HHActiveX.dll file. This file is copied to the Windows\System32 folder durin ...
11. Fixing the problem "cannot access any motor sizes"
    When you get the error "Cannot access any motor sizes", a quick fix is to force the program to reset it's install files. Reinstalling the program will not do this. This error can usually be fixed by telling the software to re-initialize itself. Users of most version 7.1 or greater versions ...
12. Run-time error when using Table Manager
    User gets the message: "Run-time error '339' Component 'tabctl32.ocx' or one of its dependencies not correctly registered: a file is missing or invalid" when using the Table Manager. To correct this issue you will need to install the tabctl32.ocx file attached to this article extracting it from ...
13. Shape Display Issue
    We've identified some problems with the way shapes, such as PUMPS display in the program. The file in this article corrects this issue. Download the file and extract it in your My Documents\My Engineering Files\Tables folder. The ESI_Shape_Override file is a custom symbol file for use with the P ...
14. Entering efficiencies for fan curve can force viscosity corrections.
    Background An issue in the way PIPE-FLO performs a check on fluid viscosity limits was discovered which may or may not force viscosity corrections on pump devices when the user models a fan, compressor, or blower with a compressible fluid. This issue is coded in versions 2007 and 2009 of PIPE-F ...
