Problem 3: Delivery roller speed anddelivery roller diameter is 200 rpm and 35mm respectively, feed roller speed and feed roller diameter 5 rpm and 70 mm respectively. Find out the production of draw frame is in kg/hour. Where, carded sliver is 50 gm/yard and machine efficiency is 80%. Calculate the mechanical draft too.
Problem 4: If the carded sliver is 55gm/m and drawn sliver weight is 45gm/m, what will be the required DCP of draw frame? When draft constant is 340.
