Practical forms of entropy production for single-membrane system and binary non-electrolyte solutions.

Linear non-equilibrium thermodynamics (LNET) has been used to express the entropy production in single-membrane system representing the true forces (mechanical and osmotic pressures difference) and flows (volume and solute flows) in a homogeneous or non-homogeneous binary non-electrolyte solution. On the basis of Kedem-Katchalsky model equations of entropy production in single-membrane system in practical forms were described.
