8 Main menu “Additional info”
8.1 Menu function “Program Pressure Drop”
This function calls up information on the program “Pressure Drop”.
Pressure Drop 6.2 for Windows calculates the pressure losses caused by the friction
of a liquid or gas flowing through a pipe (both laminar and turbulent flows); in
addition, it is possible to calculate pressure changes related to the geodetic height
(pipe runs upwards) and changes in kinetic energy.
Besides simple pipes, the program calculations take into account also the losses
attributable to pipe fittings (changes of direction, etc.) and various accessories
(valves, expansion compensator, etc.). The individual elements can be combined
freely, permitting calculation of an overall pressure drop.
To be able to calculate a pressure drop, the program requires corresponding data to
describe both the pipes (roughness) and the flow media (density, viscosity). For
typical pipes and many liquids and gases, including mixtures, these data can be
taken directly from the program's own databases. A further user-defined database
enables you to save and recall data for any individually used media.
Further infos and answers to frequently asked questions (in German, English, French
and Dutch) can be found at http://www.pressure-drop.com. The shareware version of
this program can be found in the Therm subfolder \htdocs\Druckverlust.
8.2 Menu function “Maintenance and commissioning”
This function opens a PDF file with detailed information on the topic of “Maintenance
and commissioning”. To be able to view this file, you must install the latest version of
Acrobat Reader, which can be obtained from http://get.adobe.com/uk/reader/.
8.3 Menu function “Climate engineering services”
This function opens a PDF file with detailed information on the topics “Project
planning for enclosure climate control and machine cooling”, “Thermal analysis (IR
thermography and on-site temperature measurements)” and “Preparation of CFD
analyses and flow models – Tests performed in the company's own laboratories”.
