Glass fiber rovings are commonly designated by the term yield, which is the length of the roving per unit weight (e.g., 1275 yd=lb). Estimate the yield for a glass fiber roving that contains 20 ends (strands) per roving. Each strand in the roving is made of 204 filaments, and the average filament diameter is 40 3 10 5 in.
