MCQ (Single Correct) +4 −1

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:

  • 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,
