Specific Enthalpy Calculator

How to Use the Calculator

1. Enter the temperature of the substance in degrees Celsius (°C). Make sure to use the correct unit.
2. Enter the pressure of the substance in megapascals (MPa). Again, ensure you're using the correct unit.
3. Click the "Calculate" button to compute the specific enthalpy.
4. The result will be displayed in kilojoules per kilogram (kJ/kg).
5. If you need to start over, click the "Reset" button to clear all input fields.

Working Principle

The specific enthalpy of a substance is a measure of the total energy it contains per unit mass. It is calculated based on the temperature and pressure of the substance using the formula:

h = c₁ × T + c₂ × P + c₃ × T²

In this formula, c₁, c₂, and c₃ are material-specific constants that depend on the type of substance being calculated. The calculator uses example values for these constants, but in real applications, you would need to use values appropriate for the specific material.

Example Calculation

Let's say you have water at a temperature of 50°C and a pressure of 0.5 MPa. When you enter these values into the calculator and click "Calculate," the result will be the specific enthalpy of water under these conditions.

Applications

Specific enthalpy calculations are important in various engineering fields, including:

• Thermal engineering and HVAC systems
• Chemical engineering processes
• Energy conversion systems
• Material processing industries
