Hi I have a multiple choice question on a math test at work and when I plug the numbers into the formula I am not getting a match with the choices given.
The question is:
What is the annular area in between a 2-3/8 tubing. 6.2lbs/ft, And a 1.25" coiled tubing pipe. 0109 wall thickness?
The Choices are: a) 1.47 in2 b) 3.67 in2 c) 2.19 in2 d) 5.06 cm2
