The accuracy of the two simplified methods; Dincer and Dost (1996) and Dincer and Hussain (2004), used for the determination of the first root of the characteristic equation and the Biot numbers from experimental lag factor data in unidirectional drying of solids has been investigated. The tabulated values relating the lag factor to the first root of the characteristic equation and Biot number were taken as basis in the assessment. None of the methods considered yielded accurate predictions for the complete lag factor range. The calculation of μ1 and Biot number from the tabulated values of lag factors has been recommended.
