Consider dry, atmospheric air in parallel flow over a 0.5-m-long plate whose surface is wetted. The air velocity is 35 m/s, and the air and water are each at a temperature of 300 K.

(a) Estimate the heat loss and evaporation rate per unit width of the plate, q' and n_A, respectively.

(b) Assuming the air temperature remains at 300 K. generate plots of q' and n for a range of water temperatures from 300 to 350 K, with air velocities of 10, 20, and 35 m/s.

(c) For the air velocities and air temperature of part (b), determine the water temperatures for which the heat loss will be zero.
