A properly constructed is a critical asset for process and mechanical engineers. By utilizing a "repack" or a comprehensive spreadsheet, designers can significantly reduce the time spent on iterative calculations, ensuring that the designed agitator is both efficient and structurally sound.
An Excel sheet utilizes the ASME code for shaft design to calculate the minimum required shaft diameter ( ) based on combined shear and bending stresses: This guide provides a comprehensive overview of agitator
