The material specifications for a certain aircraft require that a replacement oil line be fabricated from3/4 inch, 0.072 5052-0 aluminium alloy tubing. What is the inside dimension of this tubing?
- 0.688 inch.
- 0.606 inch.
- 0.750 inch.
Explanation
Tube size is the outside diameter, here 3/4 inch (0.750), with a wall thickness of 0.072 inch. The inside dimension equals the OD minus twice the wall: 0.750 - 2 x 0.072 = 0.750 - 0.144 = 0.606 inch.

Can someone help explain please? Thanks.

Outside diameter= .750"
Wall thickness= .072"
There are 2 walls in the diameter of the pipe, so .072" X 2 = .144"
.750" - .144" = .606"
Wall thickness= .072"
There are 2 walls in the diameter of the pipe, so .072" X 2 = .144"
.750" - .144" = .606"
