WATER AGE AND LEAKAGE IN RESERVOIRS; SOME COMPUTATIONAL ASPECTS AND PRACTICAL HINTS

H. HARIRI ASLI, S. NAZARI

Abstract


The existence of reservoirs in the water system guarantees the stability of the system. Therefore, the level of water stored in the reservoirs should always be kept at optimum level in the water system. Inside the reservoirs, the mixing operation may not perform well. The water reservoirs with low delivery time, meet to the stationary water in the corners of the reservoirs. This can lead to water corruption and increase the risk of water leakage. Another factor that can increase the water retention time in the reservoirs is the shape and geometry of the reservoirs. The main purpose of the present work is to determine the impact of reservoir design specifications on the probability of water leakage and economic losses resulting by it. In this regard, this work focused on the effect of dimension, number, and optimal location for locating baffles on water spoilage factors and probability of water leakage. As a result, the use of three baffles with the same intervals perpendicular to the flow, created the least water retention time and water age. This case is the most optimal option to reduce economic losses and water leakage probability between the investigated options.
