A laminar jet instrument was used to measure the molecular diffusivities of oxygen with 0.995 partial pressure into distilled water and aqueous solutions of eight long chained polymers. Molecular diffusivity of oxygen into distilled water was found to be 1.95 x 10m5, at 20Β°C which compares favorabl

This work deals with the measurement of diffusivity of gases (D) in polymeric solutions under flow conditions. The wetted sphere technique is used for this purpose. The relevant convective diffusion equation for pseudoplastic fluids is first solved. The theoretical results are then used in conjuncti
