Before finalizing an engineering package or approving fabrication drawings, verify the following design checkpoints:
When validating an agitator design spreadsheet or software output, always double-check these parameters: Is the ratio between 0.3 and 0.45 for turbulent flow? Q=Nq⋅N⋅D3cap Q equals cap N sub q center
