We examined pressure loss of soybeans and analyzed the data using the non-dimensioned Navier-Stokes equations for forced air in accumulations. And expressed resistance factors or friction factors of soybeans as the function of Reynolds number, to esteem a pressure loss in air forced layers of soybeans by calculation. We could get an experimental equation of resistance factor that was applied for generally to pressure loss of soybeans, in 40<Re<200 ranges which is used with usual forced air drying. We could express characteristics of pressure loss of soybeans, as the function of space rate, ratio of surface area and velocity of air by using an experimental equations of the resistance factor or a friction factor. The characteristics of pressure loss of soybeans were able to be approximated with high accuracy.
