is known, calculate the motor power required to turn the impeller through the fluid:
T=P2π⋅Ncap T equals the fraction with numerator cap P and denominator 2 pi center dot cap N end-fraction = Torque ( 3. Step-by-Step Spreadsheet Architecture The formula for an agitated vessel modifies the
The core of your Excel template should focus on the following engineering formulas: A. Impeller Reynolds Number (
A professional agitator calculation tool should be structured into three sections: Key Formulas/Lookups Vessel Size, Fluid Props, RPM User-defined constants Calculations NRecap N sub cap R e end-sub Npcap N sub p =Di5equals cap D sub i to the fifth power , Lookup tables Outputs Motor Power, Shaft Dia, Torque =SUM(...) , Safety Factors Critical Design Notes
For a single impeller overhung shaft, the critical speed is calculated using the Rayleigh method: Lookup tables Outputs Motor Power
