Sensible Heat Calculator

Your details

Physics mode uses a fixed mass. HVAC mode uses volumetric airflow for continuous cooling or heating loads.

3347.2 kJ of sensible heat added to the system.

  • 3347.2 kJ (3172.5 BTU) must be added to the substance.
  • The specific heat used is 4.1840 kJ/(kg·K). Higher specific heat means more energy is needed for the same temperature change.
  • This formula covers sensible heat only - no phase change occurs. If the substance crosses a melting or boiling point, add latent heat separately.

Next stepFor processes near phase-change temperatures, calculate the latent heat of fusion or vaporisation and add it to this result.
