SF Pressure Drop Version 5.0 for Windows 95/98/NT calculates pressure drops (caused by friction) of flowing liquids and gases in pipes. Additionally you can calculate pressure changes caused by vertical difference of the pipe and caused by changes of kinetic energy. SF Pressure Drop calculates also pressure drops in pipe elements (example: changes of direction) and diverse valves. It's possible to combine diverse elements and so to calculate the total pressure drop To calculate the pressure drop you need data of pipes (rougness) and data of flow medium ( density, viscosity). These data are available in several databases, which are editable by the user partly.An additional possibility to save your own data is the user-defined database. Additional the following futures:Quick pump design Database of pipe informations (DIN and ANSI) Calculation of pressure drop dependent on rate of flow (showing and printing of the characteristic curve) Calculation of an economic pipe-diameter at a known rate of flow Calculation of NPSH; the needed vapor pressure and weight density are available in a database Calculation of volume of pipe and filling time of the whole project or of a part of the project Conversion of rate of flow to velocity and inverse at a known pipe diameter Conversion normal-m?to working-m?Conversion kv value to resistance coefficient Conversion Cv value to resistance coefficient Input of data of pipe element and flow medium in a lot of units (metric and US units); output in metric or US units alternative Database of resistance coefficients of fittings, editable and extensible by the user Possibility to save and open SF Pressure Drop project-files.
