Tank baffles Design Calc Version 1.0 by Daniel de la Torre Process Engineer
Intro
This template contains a series of calculation sheets to assist you in calculating the baffles dimen Please note that if agitator is off-centered normally is not needed to install the baffles, as the ef
The main objectives are to provide a reference about baffles dimension and installation distance
Setup
1. There are 2 worksheets, one with Metric units (SI) and one with Imperial units
2. Individual worksheets are protected against inadvertant data entry. Unlocked cells appears with 3. To change any other cells, unlock the workbook (from the Tools/Protection pull-down menu)
4. The baffle size is calculated according to 2 methods, the one called cal 1 using the viscosity of th See Calculations point for more details
