PIPE SIZING PROGRAM The demo version of the pipe sizing program is started by inserting the disk into the A drive and giving the command PIPEDEMO. This will start the program. The program is supplied on the demo disk as a monochrome version. The program will request the type of monitor. If you have a Monochrome monitor, press the letter M when requested by the program. If you have a color system give the letter B; the program will be in Black and white. The program is unique in that it will automatically use the correct internal diameters for line sizing with different schedule pipes, and automatically uses the correct roughness values. Various fitting can be used. The Program is designed for a high degree of user friendly features. Function keys are used to chose between the various options. The F10 key must be pressed to run the program to calculate the line pressure drop, after the data is added. The program requests the required data and all fields must be filled in before pressing the F10 key or an error may result. The program will check for zero fields and request data. The return key must be pressed after inputting a data field for example the liquid flow rate, for the data to be registered. The arrow keys can be used to move around to different data fields. LIMITATIONS This program will calculate the pressure drop or lines size for simple single phase systems. High pressure drop gas systems and two phase lines require a different method. This demo disk is limited to a constant flow rate of 100 gpm. Naturally, this limitation is not present on the commercial version.
