Module summary

This module will enable the understanding of the physical laws that underpin engineering processes and how these can be used to solve chemical engineering problems.

Objectives

On completion of this module, students will be able to:
- Analyse and classify thermodynamic processes on the basis of the fundamental law of thermodynamics.
- Describe thermodynamic systems, conservation of energy, work and heat.
- Differentiate reversible from irreversible processes.
- Determine the efficiency of heat engines (including Carnot, Otto and Brayton cycles), heat pumps, refrigerators.
- Use phase diagrams to determine system properties associated with phase equilibria, e.g. vapour pressure at a specified temperature, boiling point at a specified pressure, triple point, sublimation point and critical temperature and pressure.
- Estimate vapour pressures by applying the available equation i.e. Clausius-Clapeyron, Antoine.
- Use the Gibbs phase rule to determine system degrees of freedom.

- Describe basic properties of fluids.
- Distinguish the differences between laminar and turbulent flows.
- Calculate drag force, pressure measurements and flow rate measurements with consideration to energy losses in pipe network.
- Apply the principles of fluid mechanics to solving real world problems.
- Describe the principles of diffusion as applied to fluids at rest and in laminar flow.
- Describe the modes of heat transfer: conduction, convection and radiation.
- Evaluate heat transfer through conduction; conduction through a plane wall, thermal resistance in series, steady-state conduction in composite walls, cylinders and spheres.
- Evaluate heat transfer through convection: natural and forced convection, hydrodynamic and thermal boundary layers, laminar and turbulent flow, individual and overall coefficients of heat transfer.
- Evaluate heat transfer through radiation: radiation intensity, blackbody radiation, surface absorption, reflection and transmission.
- Characterise the functional application of heat exchangers.
- Compute heat requirement in applications involving heat exchangers.

- Define diffusion and mass transfer coefficients.
- Describe molecular diffusion in fluids.
- Apply theories of mass transfer to different mass transfer phenomena.
