# FLUID MECHANICS & THERMODYNAMICS 1 - 2022/3

Module code: ENG1062

## Module Overview

First year module in thermo-fluids for MES students.

FLUID MECHANICS: The basic concepts underlying fluid flows and behaviour are described together with simple fluid properties. The calculation of static fluid forces is the starting point before moving to dynamic fluid effects including mass-flow and energy conservation. Internal flows in pipes and through pumps considering effects of fluid friction, momentum and energy losses in fittings. This will include laminar and turbulent flows and pipe system analysis.

THERMODYNAMICS: Following an introduction on energy consumption, generation and supply from conventional and alternative sources the basic principles of heat and work transfer are described and system thermal efficiency. Thermal properties of working fluids (both liquids and gases) are described. The 1st law of thermodynamics is introduced with applications to processes and cycles for closed and steady-flow systems.

## Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate understanding of scientific principles, methodologies and mathematics methods as well as the ability to describe particular systems and processes in the final examination. The Fluids in-class test and Thermo coursework elements allow students to demonstrate that they can interpret a problem and present a solution clearly and accurately.

__Summative assessment__

- Fluid mechanics online test [Learning outcomes 1, 2]
- Thermodynamics online test [Learning outcomes 1, 2]
- Examination [Learning outcomes 1, 2, 3, 4]

__Formative assessment and feedback__

- Formative verbal feedback is given in tutorials
- Formative Multiple Choice Tests are available on SurreyLearn to give feedback on understanding of simple principles
- Written feedback is given on the coursework assessments and on the in-class test answer scripts

## Module aims

- An introduction to fluid mechanics and thermodynamics and in particular internal flow behaviour and the principles and methodologies applied to fluid statics, dynamics and 1st law thermodynamics
- An understanding of the principles of energy conservation, conversion and alternative energy sources
- An introduction to the importance of system efficiency and minimization of resource requirement in engineering system design

## Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

Introduce thermo-fluid principles through theory with worked examples. This is delivered principally through lectures and tutorial classes and feedback from the thermodynamics coursework assignment and fluid mechanics in-class test.

The __learning and teaching__ methods include:

- 2 hours lecture in person per week x 11 weeks
- Pre-recorded thermodynamic lectures for flip teaching
- Pre-recorded fluid mechanics lectures
- 1 hour tutorial (in groups) x 11 weeks
- 2 hours revision lectures
- Fluids in-class test (1.5 hours) - Week 7
- Thermodynamic in-class test (1.5 hours) - Week 10

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
