Whereas within the riser region of airlift reactors the solid content was found to be constant, it shows a gradient as a function of height in the upstream region of bubble columns, which is described by the Sedimentation-Dispersion Model. In the this way for each of the two reactor types...
Such headroom shall be continuous above the stairway to the point where the line intersects the landing below, one tread depth beyond the bottom riser. The minimum clearance shall be maintained the full width of the stairway and landing. Other stair head clearance code rules Some circumstances ...
5) minimum safety height 最小安全高度 1. The calculating formulas about the risers minimum safety height and the volume ratio of the surplus molten steel were derived by establishing the solidification mathematical model of a riser-casting system and using the Chvorinov law involving the ...
