Calculation of the pressure exerted by loose granular materials on the bottom of a container
Thread Content
Assume the material is soybeans with a density of 0.6 Kg/t, and it is placed in a rectangular container with dimensions of 1m x 1m x 5m. What is the pressure exerted by the soybeans on the container? My approach is to use the formula for water: P=density*g*h; I believe that the results obtained using this formula are on the high side compared to the actual values. I would like to ask the experts for the correct calculation formula, as well as the advantages and disadvantages of using the formula P=density*g*h for calculating with water.
The force acting vertically downward is basically what the original poster mentioned; you can take a look at the information related to the silo.
The above views are merely my analogies; since I couldn’t find any relevant calculations in books on silos and storage tanks, I asked here at HaiChuan. Is it possible to provide a screenshot as evidence?
