Steam Tables Lite has evolved into Mec Eng Tools. Your water and steam tools are now part of a mechanical engineering calculation workspace. Explore eight modules organized by discipline: • Steam Tables: water and steam properties, thermodynamic states, records and diagrams. • Heat & Mass Transfer: conduction, convection, radiation, phase change, heat exchangers and mass transfer. • Steam Turbines: performance, extractions, energy balances and expansion diagrams. • Fluid Mechanics: properties, flows, pressure losses and hydraulic machinery. • Pipe Tools: dimensions, schedules and piping calculations. • Machine Design: tools for analyzing mechanical components. • Stress & Strain: models for exploring structural element behavior. • Pressure Vessels: shell and head calculations and checks available in the module. CALCULATE AND UNDERSTAND Choose a model, enter your data and review results with their units. Where applicable, select data from integrated catalogs and tables. Learn through theory, illustrations and worked examples. Save calculations and export reports in tools that support these features. YOUR STEAM TABLES IS STILL HERE The Steam Tables module retains its tools and the option to restore previous purchases. English, Portuguese and Spanish. Light and dark interfaces for iPhone and iPad. Some features require an in-app purchase. Review the included items on the purchase screen before confirming.
Linear Interpolation Master
This tool simplifies linear interpolation calculations for industrial commissioning engineers. It features large, easily readable numbers for field use and allows for quick swapping of coordinate systems, such as converting between 4-20mA and 0-100% scales.
- Large number display for field visibility
- Quickly swap X and Y coordinates
- 4-20mA to 0-100% conversion
- 0-100% to 4-20mA conversion
