SF Pressure Drop 7.x for Windows calculates pressure drops of flowing liquids and gases in pipes (laminar and turbulent flow). It's also possible to calculate pressure changes caused by vertical difference of pipe and caused by changes of kinetic energy (dynamic pressure change). SF Pressure Drop calculates also pressure drops in pipe elements (example: changes of direction) and in diverse fittings (valves, bellows etc.). A list of the calculable elements see below. It's possible to combine diverse elements and so you will get total pressure drop. To calculate pressure drop you need data of pipes (rougness) and data of flow medium (density, viscosity). These data are available in several databases. An additional possibility to save your own data is the user-defined database. Further features: Database Standard Parts (EN/ISO/DIN/ASME/ANSI) Dimensions and inner diameter of Circular pipes Rectangular pipe Bends Contractions Enlargements Tees Database of properties of liquids and gases and property calculation (density, viscosity) Calculation of properties of water and steam according Industry Standard IAPWS-IF 97 (all conditions within the range 0 to 900 °C and 0 to 1000 bar are calculable) Properties dry and humid air and air in saturation state Properties of CO2 in the range 216 K to 1100 K and 0 to 8000 bar Properties of miscellaneous liquids and gases: Besides the properties, which are available as measured values you can estimate properties of more than 300 gases and liquids at different temperature and pressure. You can also estimate mixtures. Estimation of refrigerants at different temperature and pressure Estimation of aqueous solutions Estimation of heat trensfer oils Estimation of liquid refrigerants Flexible user database for liquids ....
