Ques 48 GATE 2023
In melt spinning of a monofilament, a polymer is being extruded at a volumetric flow rate of 5 × 10⁻⁵ m³/s through a spinneret of circular cross-section. If the take up velocity of the first winder is 100 m/s with a draw ratio of 50, then the diameter (mm) of the spinneret orifice (rounded off to 2 decimal places) is _______.
Ques 49 GATE 2023
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 _______.
Ques 50 GATE 2023
In a ring frame, the speeds of traveller at 50 mm bobbin diameter (near the base of the cop) and at 25 mm bobbin diameter (near the tip of the cop) are 13500 rpm and 13400 rpm, respectively. The nominal twist (tpm) (rounded off to 2 decimal places) is _______.
Ques 51 GATE 2023

The diameters of back bottom roller, middle bottom roller and front bottom roller of the roving frame are 28 mm, 25 mm and 28 mm, respectively. If the middle bottom roller of the roving frame is eccentric, then the wavelength (m) of the periodic fault in the yarn, neglecting twist contraction, (rounded off to 2 decimal places) is _______.
