Summary

During the cooling of a carcass, both its heat losses by convection and by evaporation are governed by the convective heat transfer coefficient alpha c. While both phenomena occur at the same temperature difference delta w between the surface of the carcass and the cold air, the quantity of heat flux of the former part becomes alpha c * delta w, and the latter part becomes the product of alpha c multiplied by an equivalent temperature difference delta D which is a function of the vapour pressure differences between the wet surface and the cold air. The ratio delta D / delta w can be established from the diagram and the heat loss by convection and by evaporation can be calculated for any given value of alpha c. Consequently, the anticipated theoretical weight loss of the carcass can be calculated.
