Abstract The mass transfer rate to fluid spheres is calculated for power law and Newtonian fluids by using the intermediate Reynolds number stream functions of Nakano and Tien (1970) and Yamaguchi et al. (1974), respectively. The Sh increases with increases in Re and Pe and decreases in n . Better results are obtained with Nakano and Tien's functions when Re > 10 and with Yamaguchi's functions when Re < 10.
