EN3405 subject code deals with the Fate And Transport Of Contaminants In The Environment syllabus of B.E Environmental Engineering. In the second year, it is included in the semester IV. This subject deals with the statistics and probability concepts to explore. In this article, we include textbooks and references to guide you to some more extent.
We aim to provide a detailed syllabus of EN3405 Fate And Transport Of Contaminants In The Environment. You can find unit-wise concepts and can easily make your preparations for examinations. It wouldn’t be difficult to find all the requirements in one place for the subject syllabus. This motto makes us provide this information to make it easy for you. Hope this information is useful. Don’t regret to share it with your classmates.
If you want to know more about the syllabus of other branches including B.E Environmental Engineering connected to an affiliated institution’s four-year undergraduate degree programme. We provide you with a detailed Year-wise, semester-wise, and Subject-wise syllabus in the following link B.E Environmental Engineering Syllabus Anna University, Regulation 2021.
Aim Of Concept:
- To educate the students on the mechanism of transport and fate of contaminants in the geosphere of the environment.
EN3405 – Fate And Transport Of Contaminants In The Environment Syllabus
Unit I: Equilibrium And Transport Mechanisms
Concentration and Phase density – air-water equilibrium, Soil-water equilibrium, Earthen solid-air equilibrium. Liquid-chemical equilibrium – thermal equilibrium at environmental interfaces. Diffusion and mass transfer – molecular diffusion- Fick‚s Law – eddy diffusion – mass transfer theories -fundamentals of heat transfer –heat and mass transfer.
Unit II: Exchange Rates Between Air And Water
Desorption of gases and liquids from aerated basins and rivers – completely mixed basin – plug flow basin – gas exchange rates between the atmosphere and the surface of rivers – exchange of chemical across the air–water interface of lakes and oceans.
Unit III: Exchange Rates Between Water And The Earthern Material
Dissolution of chemicals -natural convection dissolution – water interface – mass transfer coefficients at the sediment–water interface. Flux of chemicals between sediment and the overlying seawater – movement of chemicals through the benthic boundary layer.
Unit IV: Exchange Rates Between Air And Soil
Turbulence above the air – soil interface – the Richardson number – chemical flux rates through the lower layer of the atmosphere –evaporation of liquid chemicals spilled on land – chemical flux rates through the upper layer of earthen material.
Unit V: Contaminant Transport Analysis
Potential theory- Potential Functions- Stream Function – Travel time along with Stream Functions- Residential Time Distribution Theory- Analysis of Chemical Spills and Contaminant plumes – Fourier analysis of Initial value – point spill analysis- vertically mix spill analysis- Horizontal Plane Source analysis
