= Safety factor (usually 1.15 to 1.20) to handle fluid fluctuations or startup torque under flooded conditions. 4. Mechanical Design and Shaft Integrity Calculations

A clean user interface prevents input errors and ensures the workbook remains auditable. Professional repacked spreadsheets utilize three distinct sections: Color Code Light Blue / Yellow

Note: This equation holds true for fully turbulent regimes. In laminar regimes, power is directly proportional to viscosity, and the equation modifies to Kpcap K sub p is a laminar system constant. Shaft Torque ( Mtcap M sub t
