The absorber surface of a solar collector (1.5 m long. and 0.6 m wide) is made of aluminum coated with black nickel oxide (a 0.92, & = 0.08). Solar radiation is incident on the surface at a rate of 850 W/m. The surface temperature of the absorber plate is 60 C and the air temperature is 20 C, respectively. The average air wind velocity over the plate is estimated 5 m/s. Determine the net rate of solar energy delivered by the absorber to the water circulating behind it for the following cases: = 850 W/m !!!!! Air To = 20C Absorber plate T= 60C = 0.92 &= 0.08 1. Vary the angle of the solar absorber (0) from 0 to 40 (increment of 20 ). Plot the results of net solar energy vs. angle 2. Vary the air speed from 0 m/s to 15 m/s (increment of 5 m/s). Keep other parameters constant and fix the inclination angle at 40. Plot the results of net solar energy vs. air speed.
