In 1926 E. Schmidt  discovered his optimum parabolic straight cooling fin. The most critical premise used in his analysis was the “length-of-arc” assumption that consists of neglecting the curvature of the fin exposed surface. The problem of optimum straight cooling fin design without the “length-of-arc” assumption was solved in  which led to the discovery of the optimum circular fin. In the present work, thermal efficiency of this new optimum straight cooling fin is computed.
