A Boosey & Hawkes flugelhorn that I once analysed had a bell diameter of 6 inches and a bore throgh the valves of 0.41 inches. This yields a bell diameter to bore ratio of 14.63. The ratio for the famous York CC tuba is about 26.67. Because the area of these instruments is proportional to the square of the diameter the flugelhorn cited here has 3.32 times as large an area of bell to area of tubing ratio than the York tuba.

The answer to your question if 0.6 to 0.9 (embracing the skinniest and fattest tuba valve bores times about 14.6 or roughly 9 to 13 inches bell diameter.
