• Time Consolidated Flow Function Test shows the same results as the Flow Function
Test, but shows one set of results based on the instantaneous Flow Function and one
based on the Time Consolidated Flow Function.
• A graph of a "normalized" flow function is obtained by selecting Potential Arching
Diameter from the drop-down list box located above the graph. The "normalized"
flow function provides a means for comparing powders that exhibit similar flow
function behavior, but have different density properties. The graph plots "potential
arching diameter" against "major principal consolidating stress". The mathematics
involves dividing the density of the powder at each consolidation stress into the
value for the unconfined failure strength.
