Another critical omission is . A spreadsheet designed for a 100-liter lab vessel cannot simply multiply all dimensions to reach a 10,000-liter reactor. Scale-up requires maintaining equal tip speed, power per unit volume, or Reynolds number—each yielding vastly different results. Many free .xls templates omit scale-up logic entirely, leading to catastrophic under-design. Scale-up requires maintaining equal tip speed, power per
