To calculate the surface area of a 90-degree elbow, you first determine the outer diameter and wall thickness of the pipe. The formula for the surface area of a pipe elbow is approximately \( A = \pi \times D \times (r + \frac{D}{2}) \), where \( D \) is the outer diameter and \( r \) is the radius of the bend. This formula gives you the lateral surface area, assuming the elbow has a standard bend radius.
