It is required to air condition a factory building (27m x 18m x 4m). The 27m wall is type B and facessouth. The following date is available: Two glass windows in south wall 3m x 1.5m each with internalshade, Lighting load is 20 Watt fluorescent per m2 floor area ; The inside air conditions are, DBT=24 oCand RH=50%. The outside air conditions are, DBT= 40 oC, WBT=30 oC. Other related data are: dailyRange (DR)=18.0 oC, Uwall =1.4 W/m2 k, Uglass=3.5 W/m2 k, Scglass =0.7, occupancy = 8 persons doing lightbench work and, CLFoccupancy= 0.75.

6.81 An industrial process involves evaporation of a thin water film from a contoured surface by heating it from below and forcing air across it. Laboratory measure- ments for this surface have provided the following heat transfer correlation: 0.58 NuL = 0.43 Re8 P04 The air flowing over the surface has a temperature of 290 K, a velocity of 10 m/s, and is completely dry ( = 0). The surface has a length of 1 m and a surface area of 1 m². Just enough energy is supplied to maintain its steady-state temperature at 310 K. (a) Determine the heat transfer coefficient and the rate at which the surface loses heat by convection. (b) Determine the mass transfer coefficient and the evaporation rate (kg/h) of the water on the surface. (c) Determine the rate at which heat must be supplied to the surface for these conditions.
