Assessment Criteria: It is recommended that you show all working of the numerical problem neatly on separate sheets. This problem carries 15% of the marks.Statement of Assignment:Calculate the heat transfer quantities: useful heat gain rate (qu) instantaneous efficiency of the absorber plate air outlet air temperature and pressure drop of a conventional solar air heater with the following data:Length of absorber plate= 2.5 mWidth of absorber plate= 1.6 mSpacing between absorber plate andbottom plate= 2.54 cmAir flow rate= 300 kg/hAir inlet temperature= 35 0CAmbient temperature= 14 0CSolar flux incident on collector face= 650 W/m2Angle of incidence (??)av= 0.85Top loss coefficient= 5 W/m2-KBottom loss coefficient= 0.6 W/m2-KEmissivity of top or bottom plate (?p = ?b)= 0.95Neglect heat loss from the sides.For air outlet temperature Your report must include:Complete solution of the numerical problemDiscussion of the results where appropriateMarking Scheme50% of the marks will be for evaluation of heat gain rate and efficiency of the plate20% of the marks will be for calculation of outlet air temperature.20% of the marks will be for calculation of pressure drop.10% of the marks for all working neatly and explanation of the results
