In this paper, an attempt has been made to evaluate the convective heat transfer coefficient operating in crop drying in open sun drying conditions (natural convection). Values of the constants, C and n were obtained by linear regression analysis from experimental data obtained for six crops, namely green chillies, green peas, Kabuli chana, onion, potato and cauliflower. Analysis was performed for Kabuli chana under natural cooling conditions. Based on the values of C and n convective heat transfer coefficients for these crops were determined. The experimental error in terms of percent uncertainty was calculated.
