To calc the spark length for a twin, first take 1/2 the input power. Use the formula on it, then double the result. Thus, for 10kVA, 1/2 of 10kVA = 5kVA. The sqrt of 5000 = 70.71 x 1.7 = 120" or 10 feet. Double this result to give the expected spark length of 20 feet for a twin. The reason that twins give longer sparks is because they must be thought of as two smaller coils each of half the power, each giving a spark length according to the formula. The result is doubled since the sparks meet at the center. Cheers, John Freau
