SUMMARY
The energy balance equation for the diffusion of specimens A and B across a membrane is defined by the heat flux resulting from their concentration and temperature differences. The equation is expressed as mA*(hA(TA)-hA(TB)) for specimen A and mB*(hB(TB)-hB(TA)) for specimen B, where mA and mB represent the diffusion fluxes, and hA and hB denote the specific enthalpies at respective temperatures TA and TB. This formulation assumes a steady-state condition during the diffusion process.
