Abstract
To understand the leakage of hydrochloric acid tank lorry on the road, you need to know road width, road shoulder, facility standards of road, and fluid flow. Without considering these variables, 7,510 kg leaked for 10minutes. A surface area of 631.623 m2 radians was created from the accident start point. As a result, the evaporation rate was 641.7 kg/s. However, hydrochloric acid leaking from the road flows along the road surface by several parameters. Therefore, the overall leakage is not the rate of evaporation depending on the surface area of the liquid layer spread widely from the origin of the accident. Hydrochloric acid flows by the conditions of the road. The amount is 380.4 kg. An evaporation rate of 32.511 kg/s for a surface area of 32 m2 must also be considered. So the rate of evaporation is determined by the amount of leakage on the road surface. Therefore, it can not be interpreted by the evaporation rate of a large surface area without consideration of road conditions.
