For a safe design, apply a safety factor (typically 1.2 to 1.5) to account for motor and gearbox losses. 3. Calculate Shaft Diameter
) generally falls between of the tank diameter ( ). Axial flow impellers (like propellers) are often
: The bottom-most impeller is usually placed at a height ( agitator design calculation
) The Reynolds number determines if the flow is laminar, transitional, or turbulent:
[ d_s = \left( \frac16 \times 246.2\pi \times 50 \times 10^6 \right)^1/3 = \left( \frac3939.21.57 \times 10^8 \right)^1/3 ] [ d_s = (2.51 \times 10^-5)^1/3 \approx 0.0293 , m \approx 30 , mm ] For a safe design, apply a safety factor (typically 1
