Calculate the heat-removal factor and the duct flow factor for a collector having an overall heat loss coefficient of 6 W/ (m2.K) constructed of aluminum fins and tubes. Tube to tube center distance is 15 cm; fin and tube thicknesses are 0.05 cm; tube diameter is 1.2 cm; fluid heat transfer coefficient is 1200 W/ (m2.K); and the cover transmittance to solar radiation is 0.9 and is independent of direction. The solar absorbance of the absorber plate is 0.9; the
Collector is 1 m wide and 3 m long; the water flow rate is 0.02 kg/sec. The inlet water temperature is 330 K.
