BET Model แบบจำลองทางคณิตศาสตร์ของ Brunauer-Emmett-Teller (BET)

m/mm = Ka_w/ (1-a_w) [1+ (K-1) a_w]

aw/[m (1-a_w) ]= (1/mmK) +[ (K-1) / (mmK) ] a_w

เมื่อ a_w = water activity

m       =  equilibrium moisture content (%dry basis)

mm    =  monolayer moisture content (%dry basis)

K        =  constant

C        =  constant of Guggenheim
