Analysis of water evaporation from the the odor trap using 3D printing technology

The design of foul water stacks with direct ventilation in high-rise buildings is accompanied by hydraulic assessment, based on calculating pressure resistance of odor traps with the smallest water seal height. One of the important factors in this calculation is to consider evaporation of water from the trap, which significantly reduces its pressure resistance. This article deals with the experimental measurement of water evaporation from a trap, followed by detailed analysis.
