In this paper, an attempt has been made to estimate the convective heat transfer coefficient for sensible heating of milk in a stainless steel pot during khoa, made by traditional method.Various indoor experiments were performed for simulation of a developed thermal model for maximum evaporation by varying heat Body Armor / Protection inputs from 240 watts to 420 watts.The experimental data was used to determine values of constants in the well known Nusselt expression by simple linear regression analysis and, consequently, convective heat transfer coefficients were determined.It is found that the convective heat transfer coefficients decrease with an increase in rate of heating.

The experimental error in terms of percent SOFA uncertainty was also evaluated.
