Abstract

The article deals with natural ventilation in air vents of the chimney type by applying the principle of balance of mechanical energy. The connection between the concept of discharge coefficient and the loss coefficient of duct flow is introduced. Control volume treatments have important roles. Two simple application examples are given. The article is of educational nature.
