Aims
This module teaches the fundamentals of fluid mechanics and, heat and mass transfer processes.
Fluid mechanics is one of the most important topics in Chemical Engineering. This module will equip the students with fundamental knowledge of solving common fluid flow problems in Chemical Engineering. It will begin by describing the properties of fluids such as density, pressure, viscosity, and surface tension and will then discuss various flow regimes and explain how to measure frictional energy and pressure losses in various fluid flow conditions.
This module introduces the 3 basic types of heat transfer: conduction, convection and radiation. By the end of the module the students will be able to understand many everyday examples of heat transfer, as well as being able to solve many steady state heat transfer calculations that Chemical Engineers encounter on plant.
The module will explain the processes of mass transfer and diffusion and apply them to engineering systems of separation and reactions. These principles build on knowledge of fluid behaviour and the analogy between momentum; heat and mass transfer.
Outline Of Syllabus
The Fluid Mechanics content will cover the following sections:
• Fluid Properties
• Properties of fluids in motion, including flow regimes, Reynolds number and Poiseuille equation.
• Continuity equations (conservation of mass), fluid energy (pressure, kinetic, and potential energies), Mechanical Energy Balance, and Bernoulli’s equation
• Conservation of momentum, friction factor in pipes, pressure drop due to friction, and Moody chart
• Minor losses (sudden expansions/contractions, valves, and fittings), loss coefficient, and equivalent length
• Flow measurement (orifice plates, flow nozzles, Venturi tubes, and Pitot tubes).
The Heat Transfer content will cover the following sections:
• An introduction to heat transfer, the 3 modes of heat transfer and why the study of heat transfer is important for chemical engineers
• The fundamentals of conduction including Fourier’s Equation, conduction through different 1D geometries, composite systems and thermal resistance
• The funamentals of convection including Newton’s Law of Cooling, combined convection and conduction, and convection correlations
• Heat Exchanger Design including the overall heat transfer coefficient, the log mean temperature difference and sizing of simple heat exchangers
• Extended surfaces.
The mass transfer content will cover the following sections:
• Diffusion and diffusion coefficients
• Ficks 1st law and equimolar counter diffusion. Diffusion through a stationary phase and Stefan’s Law. Two film theory
• Individual and overall mass transfer coefficients. Application of mass transfer coefficients.

Teaching Rationale And Relationship
Lectures convey the basic concepts of fluid mechanics and, heat and mass transfer, and demonstrate their application in chemical engineering context whilst tutorial classes support the lecture material through extended examples. The key concepts are presented in person, to allow discussion with students and in-person questioning. All tutorial classes are also held in-person, to ensure students receive the help they need to successfully attempt the extended example problems.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The exam at the end of semester 2 is an appropriate way to assess mathematical and analytical skills applied in combination with assessment of the fundamental knowledge of fluid mechanics, heat transfer and mass transfer. In particular, the exam allows the students to be suitably tested by undertaking unseen problems.
The computer assessment will allow students to test their knowledge during the term, helping them to identify gaps in their knowledge and areas for improvement prior to the end of term exam.
