Step by step shell and tube heat exchanger design and analysis software Below is a list of some functions: 1-Step by step calculation 2-Estimate the Physical properties of more than 1450 components; the database has the ability to estimate Thermal Conductivity, Density, Heat Capacity and Viscosity. The database also included critical properties, boiling and melting points. 3-Estimate mixture properties. (ALL ESTIMATION METHODS CURRENTLY SUPPORT LIQUIDS ONLY) 4-Integrated customised database functions to allow user to add/delete compnents. 5-Ability to import properties to Shell/Tube sides form Microsoft Excel 6-Export Results summary to Microsoft Excel 7-Ability to calculate unknown shell or tube side temperatures by iteration method (solving by trial and error) 8-Also can select from different correlations to calculate shell or tube heat transfer coefficient 9-Calculate the scale resistance (dirt factor) 10-Shell/Tube side Reynolds and Nusselt numbers 11-Buffle spacing 12-Recommended minimun shell thickness, minimum recommended number and diameter of rods. 13-Calculate Shell / Nozzle / Channel / Head / Tubesheet Thickness. 14-Support S.I Units and English (U.S) Units of mesurement. 15-Duty Calculation 16-Overall heat transfer coefficient 17-Shell/Tube velocities. 18-Save/Load results. 19-Generate/Print a summary of results
