Question #3 [13 marks] | 30 minutes 46 minutes for uploading A solar collector as shown in the figure is used for a heating process where atmospheric air of kg/s and TI-30°C flowing through a rectangular channel of size (L- 300 cm,w* 60 cm and H-10 cm). The bottom surface of the channel is well insulated, while the top surface is subjected to a uniform heat flux of [XXX] W/m2. Assuming fully developed flow, determine: a) Determine the air outlet temperature. [3 marks] b) Calculate the convective heat transfer coefficient. [7 marks] c) Determine the surface temperature of the plate at the outlet. 3 marks] Using the air properties: [ -0.02588 W/mK: -1.007 kJ/kg-K:P, -0.7282: 1. - 1872 105kg/ms] Hint:[XXX)= the last three numbers of your ID.
