Comparison of the laboratory experimental dust concentrations with 95 percent confidence intervals and the CFD modeled concentrations.

Case 1: 300 cfm 2:1 3:1 4:1
Lab-averaged value, with 95 percent confidence interval (mg/m3). 3.98, 4.56-3.40 0.72, 1.39-0.04 0.30, 0.49-0.11
CFD (mg/m3). 4.07 0.30 0.00
Inside/outside 95 percent CI. Inside. Inside. Outside.
