Anchor Agitator Design Calculation Xls Work Jun 2026When the viscosity exceeds 10,000 cP (centipoise), standard propellers simply bore holes in the fluid without moving the bulk. An anchor agitator, due to its large diameter (typically 90% to 98% of the tank diameter), physically pushes the fluid, ensuring: [ T = 7970 / (2\pi \cdot 0.333) \approx 7970 / 2.09 \approx 3813 , \textNm ] For single square-bar anchor, ( N_p \cdot Re_m \approx 300 ). So ( N_p = 300 / 10.8 \approx 27.8 ). This is the energy required to turn the impeller. $$ P = N_p \cdot \rho \cdot N^3 \cdot D^5 $$ Note: In laminar flow, power is directly proportional to viscosity and speed. For engineers, the phrase represents more than just a search query—it is a quest for a practical, reusable tool. An Excel spreadsheet (XLS) for anchor agitator design simplifies tedious manual iterations, integrates empirical correlations, and ensures compliance with standards like API 650 or ASME Section VIII. The core of your Excel sheet should focus on the power required to rotate the impeller through the viscous medium. Reynolds Number ( NRecap N sub cap R e end-sub |
