Bioprocess Model

INSTURCTIONS: Click Bioprocess Conditions toolbar, set conditions, click buttons below graph to plot results. Below are outputs. Under the outputs are the Vessel Conditions. Click the various toolbars to set scale-up conditions. Click "Set Conditions" to set Vessel conditions, and then any of the buttons below the Bioprocess Model Graph to plot results.

Set Power # to 0 if there is no impeller.
% Diameter is the diameter of impeller in relation to the inner diameter of the vessel.
Spacing is in relation to the diameter of the impeller (e.g. 1 = 1 diameter spacing).
