Please, kindly let a sure expert help solve this problem clearly answering all the questions a - m, and in legible hand writing. Thank you.

a = = = For a solar flat plate collector having the following characteristics and ignoring the bond resistance, calculate the fin efficiency, the collector efficiency factor and the collector heat removal factor. Also calculate the useful energy and thermal efficiency of the collector a. Overall loss coefficient, UL = 7 W/mK b. Tube spacing = 120 mm c. Tube outer diameter = 20 mm d. Tube inside diameter = 17 mm e. Absorber plate thickness = 0.5 mm f. Absorber plate material is copper having a thermal conductivity of 385 W/m K g. Convective heat transfer coefficient inside the tubes = 400 W/m2K h. Collector area = 6 m2 i. Mass flow rate of water entering the collector = 0.05 kg/s j. Specific heat of water entering the collector = 4184 J/kg K k. Teovlabs = 0.8 1. Global solar radiation incident on the collector for 1 h is 3.0 MJ/m h m. The collector operates at a temperature difference (Tri - Tamb) of 8C
