A droplet of water is placed in dry stagnant air of constant tempera- ture Tr. The droplet evaporates and cools to an equilibrium tempera- ture T. (a) To estimate T, derive the equation -kair Nu(Tw-T) = AD12Pair Sh 1 W10 - Wis 1 - @ 10 Sh where A is the water latent heat of vaporization, Nu = hD/k, and 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 سخ داده 20.00 امت زدن
