ABSTRACT TWO grain pressure parameters, bulk density and the sidewall friction coefficient, were evaluated for soft red winter wheat. Functional relationships were developed for the grain parameters as they were allowed to vary with the internal pressure of the grain, speed of travel of the grain down the sidewall, and the moisture content of the grain. These parameters were allowed to vary over a range of 7 to 172 kPa, 0.06 to 6 m/h and 8 to 24% wet basis moisture content, respectively.
