Diffusion rates of water in three varieties of corn, K-4 hybrid popcorn, Gold Rash sweet corn, and K-1859 hybrid corn, and two varieties of sorghum, white kafir and Atlas sorgo, were measured under temperatures ranging from 0 to 100 C. The approximate diffusion equation derived for particles with arbitrary shape was found valid at the initial period (up to approximately 2 hr.) of steeping grains in water at all the temperature levels. The diffusivities were evaluated from the data by use of the equation. The diffusivities were well correlated according to the Arrhenius law.
