Agitator Design Calculation Xls -

): Ensure your operating speed is safely away from the shaft's natural frequency. Most designs aim to operate at less than 70% of the critical speed to avoid catastrophic vibration. Calculate the maximum deflection ( Δcap delta

To determine the flow regime (laminar, transitional, or turbulent), calculate the impeller Reynolds number: agitator design calculation xls

The agitator_design_calculation.xls tool, built according to this specification, will allow for the rapid sizing of agitator components. It is recommended to add a safety factor of at least 20% to the final motor selection to account for process upsets or variations in fluid properties. ): Ensure your operating speed is safely away

For , use Zwietering’s equation – not included here. It is recommended to add a safety factor

[ t_blend = 5.2 \times \left( \fracTD \right)^2 \times \frac1N ] Example: ( t_blend = 5.2 \times (2.0/0.67)^2 \times (1/2.5) \approx 18.5 , \textseconds )

From Q, the spreadsheet estimates for 95% homogeneity: θ95 = (5.4 * (T/D)^2 * V) / Q (approximate correlation).
