Question: 1. Let a piece of ice uniformly at 0°C be immersed in water at 27°C. Evaluate the rate at which melting occurs in terms of the conductance g. How would you evaluate g?
2. A wet surface is to be dried by blowing dry air at 32° C over it, while at the same time electrically heating it from the rear with a fixed heat flux of 25,000W/m2. Investigate the variation of the drying rate m" as the conductaIlce g is varied (presumably by varying the air velocity).
