Evaporation and heat transfer: exam problem solving

This lecture covers the analysis of two exam exercises related to evaporation and heat transfer. The first exercise involves a drop of water on a hot plate, discussing the survival time of the drop and the heat flux balance. The second exercise focuses on evaluating the mass flux and convective heat flux, considering the Grasshoff number and the Nusselt number. The lecture also delves into the analytical solution of the problem using oblate spheroidal coordinates and the evaluation of total evaporation flux. Various concepts such as the Reynolds number, Schmidt number, and boundary layer thickness are explored in the context of the exercises.
