MCQOPTIONS

1.	A solid is being dried in the linear drying rate regime from moisture content X o to X F . The drying rate is zero at X = 0 and the critical moisture content is the same as the initial moisture X o . The drying time for M = ( L s / AR c ) is (where, L = total mass of dry solid, A = total surface area for drying R c = Constant maximum drying rate per unit area X = moisture content (in mass of water/mass of dry solids))
A.	M ( X o - X F )
B.	M ( X o / X F )
C.	M ln( X o / X F )
D.	MX o ln( X o / X F )
