Popis:	A fully developed turbulent flow of an electrolyte solution in a porous-wall tube with suction or injection flow through the wall was experimentally studied. The measurements of mass transfer rates at the wall were made by an electrochemical method. Reynolds number were varied from 7900 to 21, 000 and Schmidt numbers were 750, 1100, 1920 and 2100. The mass flow ratios ρvw/ρU ranged from -2.13×10-5 to 5.59×10-5. It was recognized that mass transfer coefficients at the wall rise with increase of suction rate and fall with increase of injection rate. The results are in good agreement with predictions by film theory.
