A spherical slice with radius 3.2 cm of a carrot was dried by using tunnel drying. During process free moisture content (Xf, kg H2O / kg dry matter) and time (second) were recorded as given below. The net weight of slice was 15.07 gram with 21% dry matter and 5 cm length. a) Plot the data on Excel; Xf vs time, Drying Rate (kg H2O / sec.m3) vs Xf.(Show your graphs!) b) Calculate diffusion coefficient (m2 /sec) of carrot slice (You do not have to show lnX* vs t graph).
