... by 36% when the surface area increased from a tube diameter of 8 mm to 17.8 mm. Also, the temperature distribution in the turbulent regime remains constant from the highest point to the bottom point. However, it significantly differs in laminar flow. A suitable correlation is suggested for the variation...
