Tank baffles Design CalcVersion 1.0
by Daniel de la TorreProcess Engineer
Intro This template contains a series of calculation sheets to assist you in calculating the baffles dimension and position in a tank, when the tank has a central agitatorPlease note that if agitator is off-centered normally is not needed to install the baffles, as the effect is relatively similar, with a more clean installation
The main objectives are to provide a reference about baffles dimension and installation distances details a compare results between more than one calculation method
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 blue text color. No password needed to unlock
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 the product, while the one called calc 2 not using it See Calculations point for more details
Data Entry 5 Input data appears with blue text color
Results 6 Results appear in black text with yellow backgound
Revisions 7 Version 1.0 First version
Calculations 8 Calculations are based on following assumptions
