# Finding fin area and total area for a plate and fin heat exchanger

hey all,
I am actually trying to validate the results for a plate and fin heat
exchanger.I am trying to calculate the gas side and air side fin area
and total area.
my question would be
1.how to calculate the fin area and total area.what are the things yo
uconsider when u calculate these.
2.I was wondering whether fin density and fin thicknes are realted to
this calculations.
3.I am actually trying to calculate for a plain fin.I can give the
values so that if you can play around with ur idea.
4.Fin Density=0.615 per mm ; Fin metal Thickness=0.152 mm:hydraulic dia
=0.002383 mm
he gave a direct value for Fin area/total area =0.923
I want to know how he got 0.923
thank you
