Course Description

This course is an introduction to the thermodynamics of fluids for chemical engineering applications. Concepts to be learned include heat, work, internal energy, enthalpy, entropy and state functions. Students will understand how to calculate heat and work effects arising from physical processes such as expansion and contraction of fluids and how to calculate the thermodynamic properties of fluids using equations of state, residual properties and correlations.  Course concepts will be reinforced in a project. (0/0/0/42/0). Prerequisites CHEE 221 (or MINE 201)

Objectives and Outcomes

This course reinforces thermodynamic concepts introduced in first year, and extends them to the use of fluids in practical applications. The impact on thermodynamics on the analysis and design of chemical engineering processes such as power production (e.g., Rankine Cycle Powerplants and Gas Turbines) and refrigeration systems is emphasized, with the aim of achieving improved performance.

Specific course learning outcomes include:

  1. Explain the phase rule and the fundamental concepts used in a phase diagram including critical state, supercritical fluid, phase transition and triple point.
  2. Describe the concept of a generalized equation of state and the laws of corresponding states to represent non-ideal fluid behaviour.
  3. Acquire a deeper understanding of the Second Law of Thermodynamics that includes Carnot’s Theorem and the concept of entropy and its implications to process efficiency of unit operations such as pumps, compressors, turboexpanders, and throttles.
  4. Calculate values of heat, work, enthalpy, entropy and other thermodynamic properties and quantities. Apply the concept of residual properties to calculate the efficiency of processes.
  5. Apply the fundamental concepts of thermodynamics to solving material, energy and entropy balances for process components.
  6. Apply the combined material, energy and entropy balance equations to solve process flow diagrams for basic power plants and refrigeration.
  7. Describe and analyze the performance the Rankine cycle, the Brayton Cycles and other simple cycles. Understand the concept of coefficient of performance.

This course assesses the following attributes:
