In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the circles. Generalisations can be made to higher dimensions – this is called sph… WebPercentage efficiency = n / 4 x 100 = 78.5 % Therefore the efficiency in case of square packing is 78.5% Case 2 Hexagonal packing Here we determine the sides of the base of the container in terms of the radius of the cylindrical tin. One side of …
