Calculate the heat-removal factor for a collector having anoverall heat loss coefficient of 10 W/m2 K and constructed ofcopper fins and tubes (k = 390 W/m?K). Tube-to-tube center distanceis 12 cm, fin thickness is 0.05 cm, tube diameter is 1.5 cm, andfluid-tube heat transfer coefficient is 1000 W/m2K. The covertransmittance to solar radiation is 0.8 and is independent ofdirection. The solar absorptance of the absorber plate is 0.9, thecollector is 1 m wide and 2 m long, and the water flow rate is 0.03kg/s. The water temperature is 330 K.
