I was working this Grainger problem on inductive reactance in the line but for the second part of the question doesn't give the GMR and they do not tell you the ASCR is a "Dove" but they do give enough information to do the first part of the question by telling us it a "Blue jay" but with there no information telling you what type of bird to use to find the ASCR . Does anyone knows how you can find the GMR to solve the equation for the dove?

You would need a cutsheet of the ACSR birds. A bluejay KCMIL is 1113 KCMIL. If you are bundling two for the other line, divide 1113 by 2 to get 556.5 kcmil. ACSR with 556.5 kcmil includes Osprey, Parakeet, Dove, and Eagle. The question states the two conductor bundle is ACSR 26/7, which narrows it down to Dove, as the other birds have different strandings.
