( where A is the water latent heat of vaporization, Nu=hD/k, and Sh Dhp/D12, neglecting both thermal radiation (it is likely to be considerable since convection is so low in a stagnant situation) and blowing effects on heat transfer. (b) Show that the result of part a can be reduced to = Cpai (Tw - Ts) A = Le @ 10 F Wis 1 - @ 10 where the Lewis number Le is defined as Le = D₁2/a and a = k/pCp. (c) For the case of T 70°F, determine the value of T (an iterative solution procedure is required since w₁o depends on the unknown T). How long will a 0.1-in.-diameter droplet last if evaporating at this equilibrium rate?
