Energy Quantity + Energy Quality

Find the Exergy Factor of an energy stream.

Choose the energy form and enter what you know. For heat or cooling, add the temperatures. The calculator gives you fx and the accessible exergy.

Required Inputs

Exergy Factor 1.0
Exergy Factor Notation 1 MWh_e, fx = 1.0
Accessible Exergy 1 MWh_ex

fx measures the stream's thermodynamic distinction from its declared reference. If the states are indistinguishable, fx = 0 and no work potential remains.
