Introduction to Engineering Thermodynamics

Claire Yu Yan

A free introduction to engineering thermodynamics, building energy and entropy balances through worked examples and interactive practice.

Prerequisites: Algebra, units, basic calculus and introductory physics. Be ready to read property tables and distinguish a physical system from its surroundings; previous thermodynamics is not required.

Engineering thermodynamics: choose a book and build an energy balance

Compare a free foundation with two full textbooks, follow six study stages, and check an original energy balance with units and assumptions.

Study route and exercise: University Reading List editorial project.

Who this book is for

For an undergraduate student taking a first one-term course in engineering thermodynamics, or a reader rebuilding the foundations before a larger reference. The concise progression is useful when energy calculations feel like a collection of unrelated formulas. It makes a free companion for practising the reasoning behind a balance equation.

Prerequisites

Algebra, units, basic calculus and introductory physics. Be ready to read property tables and distinguish a physical system from its surroundings; previous thermodynamics is not required.

What it covers

The text moves from state properties and substance models to the first law for closed systems and control volumes, then entropy and the second law. Worked engineering examples connect a diagram and property choice with the quantities entering a balance.

How to use it

Begin each problem by drawing the boundary and stating whether mass crosses it. List assumptions about steady operation, heat transfer and changes in kinetic or potential energy before simplifying the equation. Identify the state independently of the process, select appropriate data, and check that a plausible energy answer also satisfies the entropy constraint. Rework one example with a different boundary to compare the bookkeeping.
