Material Energy Balance is an Android application developed by Engineering Hub. The app provides engineering students with comprehensive notes on material and energy balance. The content is structured in a chapter-wise manner, covering important topics in the field. The app covers topics such as mathematical and engineering calculations, ideal gases and vapor pressure, material balance, energy balance, and stoichiometry & unit operations.

The first chapter of the app covers mathematical and engineering calculations, including different unit systems, conversion of units, the law of conservation of mass, and energy basics. The second chapter covers ideal gases and vapor pressure, including the introduction of ideal gas, behavior of ideal gases, and real gases. The third chapter covers material balance, including the introduction of component balance solving material balance and unsteady state recycle bypass and purge calculations. The fourth chapter covers energy balance, including specific heat capacity, heat and enthalpy changes, and heat of vaporization. Finally, the fifth chapter covers stoichiometry & unit operations, including crystallization, evaporation, and psychometry.

Overall, Material Energy Balance is a useful app for engineering students looking for comprehensive notes on material and energy balance. The app is free and available on the Android platform.
