In a roving frame, the ratio of the diameter of the top (driver) cone-drum to the diameter of the bottom (driven) cone-drum is inversely proportional to bobbin diameter. At an instant,
Top cone-drum diameter = 212 mm;
Bottom cone-drum diameter = 108 mm;
Bobbin diameter = 54 mm;
When the bobbin diameter becomes 100 mm, the ratio of the top cone-drum diameter to the bottom cone-drum diameter (up to 2 decimal places) is _______.
Top cone-drum diameter = 212 mm;
Bottom cone-drum diameter = 108 mm;
Bobbin diameter = 54 mm;
When the bobbin diameter becomes 100 mm, the ratio of the top cone-drum diameter to the bottom cone-drum diameter (up to 2 decimal places) is _______.
