Consider the drying operation shown in the figure below for a solid loading (dry basis) of  50 kg/m$^{2}$ with a constant drying rate of 5 kg/m$^{2}$.h. The falling rate of drying is linear with moisture content..

The drying time(in hrs) required to reduce an initial moisture content of 25% to a final moisture content of 2% is

1. 1.55
2. 1.75
3. 3.25
4. 4.55
