Chapter 12, Problem 12.146(choose chapter or problem)
Our students perform a laboratory experiment todetermine mass transfer from a wet paper towel expe-riencing forced convection and irradiation from radi-ant lamps. For the values of T?and Twbprescribedon the sketch, the towel temperature was found to be Ts?310 K. In addition, flat-plate correlationsyielded average heat and mass transfer convectioncoefficients of and respectively. The towel has dimensions of92.5 mm?92.5 mm and is diffuse and gray with anemissivity of 0.96.(a) From the foregoing results, determine the vapordensities, ?A,sand ?A,?, the evaporation rate, nA(kg/s), and the net rate of radiation transfer to thetowel, qrad(W).(b) Using results from part (a) and assuming that theirradiation Gis uniform over the towel, deter-mine the emissive power E, the irradiation G, andthe radiosity J.
