Hello~

 

I am studying about heat transfer from agitated jacket vessel.

Studying documents are website( http://www.cheresour...-vessel-design?) amd magazine(Heat transfer agitated jacket vessels). 

The formula of 1.86* ((Nre * Npr * (De / L)) ^ 0.33 * (u / uw) ' is used to case of 'Annular jacket with spiral baffling'

Where, Nre = Reynolds number

             Npr= Prandtl number

             De = Equivalent diameter

             L    = Length of jacket passage

             u    = Viscosity of jacket fluid

             uw  = Viscosity of jacket wall

 

-> Reference  http://www.cheresour...sel-design?pg=2

 

But, I don't know about 'L(Length of jacket passage). What is define of 'Length of jacket passage'

And how do you calculate?

 

 

Thank you for reading message

 

Have a good day~!
