Relative size and placement of impellers in a tank affects power draw, blend time, pumping capacity, solids suspension capability, vortex formation and maybe a few other things. Some parameters are more sensitive to geometry than others. The dimensionless geometric ratios used in calculations include D/T, Z/T, C/T, S/D, O/T, and W/D. As long as the same units are used for numerator and denominator, it does not matter what system of units is used.
