The concentration difference power is power generation which use osmotic pressure generated when having carried out sea water and fresh water by the semi-permeable membrane and turn the turbine In this power generation, the amount of osmosis of fresh water is important. By this research, it is proposed a model of the feed water flow and the osmosis from a hollow fiber into the sea water in pressure retarded osmosis (PRO). The influence of the diameter and the internal pressure of the hollow fiber are examined for osmotic flux and power of PRO. It is clear of the existence of the maximum flux for internal pressure.
