Equation for predicting EMC of agricultural products is given by
(A) . Kelvin
(B) . Harkins-Jura
(C) . Henderson
(D) . Janssen
Choose the correct answer from the options given below:
EXPLANATION
Sorption Thermodynamics & Moisture States
- Equilibrium Moisture Content (EMC) Isotherm Models:
- The equilibrium moisture content of agricultural grains is predicted by empirical and theoretical sorption isotherm equations:
- Kelvin equation: Based on capillary condensation in pores.
- Harkins-Jura equation: Based on multimolecular adsorption potential.
- Henderson equation (Modified Henderson equation): Most widely used empirical model for grain sorption isotherms.
- (D) Janssen equation: Calculates grain pressure in deep storage bins, not EMC.
- Conclusion: (A), (B) and (C) only (Option 3).
Correct option: (3) (A), (B) and (C) only,
