## What is Mec Eng Tools?

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.
