This paper studies the effect of some of the variables on the rate of air flow through the chimney. A test table consisting of an electrically heated base was replaced and replaced by solar energy and a solar chimney was placed on top of it. Both the height of the chimney - the diameter of the chimney - the ratio of chimney diameters and the area of the base surface have been changed. From the study, it was found that the air flow rate, the heat transfer coefficient and the number of Noslet were increased with both the heat flux density and the modified Rayleigh number. Also, from the practical results it was concluded that the amount of air flowing through the chimney increases with increasing chimney height and decreasing chimney diameter as the amount of air flow decreases at Changing the ratio of the diagonal of the chimney at a fixed height. Also, it is possible from the results to conclude that the amount of air flowing through the chimney increases with an increase in the ratio of the area of the heated base to the diameter of the chimney.
