Environmental Engineering Fundamentals: Conservation of Mass

Every environmental engineering solution relies on a fundamental truth: matter cannot be created or destroyed. Understanding how substances move, dilute, and react in air, water, and soil is crucial for designing effective treatment systems and predicting pollutant pathways. This text-based course guides you from core scientific principles to practical engineering calculations. You will begin with foundational definitions, learning how to define control volumes and formulate basic mass balance equations. Next, you will explore transport mechanisms like advection and diffusion, as well as modern modeling concepts such as retrieval-augmented data analysis for environmental monitoring. What you'll learn: Understand core conservation of mass principles and define control volumes; Formulate steady-state and transient mass balance equations; Analyze pollutant transport through advection, diffusion, and dispersion mechanisms; Apply mass balance concepts to water quality and air pollution scenarios; Calculate chemical reaction rates and decay within environmental systems; Practice solving engineering problems using structured, step-by-step mathematical models. This course begins with essential terminology before moving on to practical calculations and real-world environmental scenarios. It is designed for beginners, students, and aspiring civil or environmental engineers, with no prior engineering background required.
