Abstract (2. Language): 
in this study we have been indicated an effect of tilt angle and the mass flow rates onto the thermal performance of a single pass solar air heater will be investigated experimentally. The effects of mass flow rate of air on the outlet temperature, the heat transfer in a solar collector and thermal efficiency were studied. Experiments were performed for range of air mass flow rates from 0.0078 to 0.0166 kg/s., Moreover; the maximum efficiency was obtained at the difference’s mass flow rates. The maximum efficiency obtained for the 0.0078, 0.0093, 0.0125 and 0.0166 kg/s were 47.82%, 37.50%, 31% and 26% respectively. Comparison of the results as an effect the mass flow rates by solar collectors and the tilt angle a substantial enhancement in the thermal efficiency. The optimal tilt angles for the outlet temperature were between 20 and 30°.
