What is the relationship between equilibrium moisture content (EMC) and free moisture content (FMC)?

What is the relationship between equilibrium moisture content (EMC) and free moisture content (FMC)? Correct Answer FMC=Total water content -EMC

EMC (equilibrium moisture content) of a hygroscopic substance is defined as the substance that is surrounded at least partially by air where it neither gains nor loses the moisture. FMC(free moisture content) is the amount of water that is free to evaporate from solid.

200 kg of solids (on dry basis) is subjected to a drying process for a period of 5000 seconds. The drying occurs in the constant rate period with the drying rate as, Nc = 0.5 × 10-3 kg/m2.s. The initial moisture content of the solid is 0.2 kg moisture/kg dry solid. The interfacial area available for drying is 4 m2/1000 kg of dry solid. The moisture content at the end of the drying period is (in kg moisture/kg dry solid)
