# Specific Enthalpy Calculator

## About Specific Enthalpy Calculator (Formula)

The Specific Enthalpy Calculator is a tool used to determine the enthalpy content per unit mass of a substance. Enthalpy is a thermodynamic property that represents the total energy of a system, including both internal energy and pressure-volume work. The formula for calculating specific enthalpy is as follows:

Specific Enthalpy = Internal Energy + (Pressure × Specific Volume)

Where:

• Specific Enthalpy: The enthalpy content per unit mass of the substance, usually measured in joules per kilogram (J/kg) or other relevant units.
• Internal Energy: The internal energy per unit mass of the substance.
• Pressure: The pressure of the substance, often measured in pascals (Pa).
• Specific Volume: The volume per unit mass of the substance.

This calculation is used in thermodynamics to analyze energy changes in processes involving gases, liquids, and solids. Specific enthalpy is particularly important in studying heat transfer, phase changes, and energy interactions.

The Specific Enthalpy Calculator simplifies the process of determining specific enthalpy values, aiding engineers, researchers, and students in thermodynamics and energy-related fields to analyze energy changes and make informed decisions about system behavior.
