The answer is: Travel = Offset x Constant
The constant for a 45 degree angle fittings 1.4142 (shorten to 1.41)
1) - measure the offset (distance pipe is being moved to new location c-c)
2) - multiple the offset by the constant 1.41
3) - answer is the travel measurement or "the distance between the two 45)
i.e: if the offset is 7 1/2" then T= 7.5 x 1.41 = 9.87 round off to nearest 1/8' T=9 7/8" c-c
Hope this helps. by the way this formulas works for any travel measurement, only thing that changes is the constant being used.
