Dynamics of changes in excess pressure in the osmotic cell with leaks

The problem of pressure increase dynamics in the measuring cell in osmotic phenomena for real membranes (with leaks) is considered. Cases of both small and considerable leaks as compared to the osmotic flow are considered. It is shown that the experiment confirms the theory. The results of the paper suggest that the measurement methods used by various authors may give an irreproachable result due to the kinetic features of the osmotic process.
