Question

A meter of polyaramide fiber has a diameter of 350 um, a mass of , and takes to produce on an industrial spinneret. How would you calculate the mass of fiber that can be spun in ?

Answer 1

Answer:

Let's work out the mass produced every second first.

To do that we multiply the mass produced in .31 seconds by 1 divided by .31

0.133g x 1 / .31 = .133/.31

Fractions with decimal places can be simplified by shifting the numbers to the left. As long as we move the numerator and denominator the same number of places then the fraction stays equivalent.

That's 133/310 grams of fibre (UK spelling) every second.

Multiply that by the number of seconds in 60 minutes (3600) and you have your answer

133 x 3600 / 310 = 478800/310 grams in 60 minutes

1544.516 g
