The replacement oil line must be fabricated from 3/4 in 0.072 5052-0 aluminum alloy tubing. What is the inside dimension of this tubing?

Explanation:
The inside dimension is found by subtracting twice the wall thickness from the outside diameter. The tube has an outside diameter of 0.750 inches and a wall thickness of 0.072 inches. So ID = 0.750 − 2 × 0.072 = 0.750 − 0.144 = 0.606 inches. Therefore, the inside dimension is 0.606 inches.
