The characteristics of the practical flow of the drainage in stacks vary with the inflow conditions and the plumbing systems. In this report the authors tentatively assumed that the drainage in stacks was two phase flow as annulus composed of water and air, and analysed the characteristics of it from the experimental and theoretical viewpoints. 1) The authors obtained the equations in order to calculate the therminal velocity and the terminal length from the flow quantity of water. 2) The flow quantity of air induced by the water was roughly estimated from the fllow quantity of water and the terminal velocity. 3) It was proper to express the flow characteristics in stacks with the occupant ratio of water.
