Unit 4025 Operations and Plant Management Assignment Brief

Introduction

The challenges of modern manufacturing industries require today’s operations engineers to adopt a multi-skilled methodology when dealing with the array of complex engineering problems they are faced with. Long gone are the days of ‘pure’ mechanical or electrical maintenance staff; operations engineers may well specialise within one discipline, but they must have the knowledge and ability to safely tackle problems that could encompass many varied engineering fields if they are to keep  the wheels of industry in motion.

The underlying aims of this unit are to develop the students’ knowledge of the engineering fundamentals that augment the design and operation of plant engineering systems, and to furnish them with the tools and techniques to  maintain the ever more technological equipment.

The students are introduced to the concept of thermodynamic systems and their properties in the first learning outcome; this will provide a platform for the topic of heat transfer in industrial applications (as covered in learning outcome four) and underpin their future studies in subsequent units. The second learning outcome examines common mechanical power transmission system elements found in numerous production/manufacturing environments, whilst the third learning outcome investigates fundamental static and dynamic fluid systems.

On completion of this unit students will be able to learn about the fundaments that underpin the operation of the systems they deal with on a daily basis and apply these fundamentals to the successful maintenance of the systems.

Learning Outcomes

Essential Content

LO1 Analyse fundamental thermodynamic systems and their properties

Fundamental system:

• Forms of energy and basic definitions
• Definitions of systems (open and closed, isolated) and surroundings
• First and second laws of thermodynamics
• The gas laws: Charles’ Law, Boyle’s Law, general gas law and the Characteristic Gas Equation
• The importance and applications of pressure/volume diagrams and the concept of work done
• Polytropic processes: constant pressure, constant volume, adiabatic and isothermal processes
• Use problem solving tools for analysis where relevant – for example, as Root Cause Analysis (RCA) Process Failure Modes Effects Analysis (PFMEA), Fishbone, Practical Problem Solving (PPS) and Advanced Product Quality Planning (APQP)
• Relate knowledge and skills on thermodynamics systems to operations and plant management through real-world industry scenarios.

LO2 Investigate power transmission systems

Power transmission:

• Flat and v-section belts drives: maximum power and initial tension requirements
• Types of power transmissions: mechanical, hydraulic, pneumatic, electrical
• Constant wear and constant pressure theories
• Gear trains: simple and compound gear trains; determination of velocity ratio; torque and power
• Friction clutches: flat, single, and multi-plate clutches; maximum power transmitted
• Conical clutches: maximum power transmitted
• Relate knowledge and skills on power transmission systems to operations and plant management through real-world industry scenarios.

LO3 Determine the parameters of static and dynamic fluid systems

Fluid flow theory:

• Continuity equations
• Application of Bernoulli’s Equation
• Reynolds number; turbulent and laminar flow
• Measuring devices for fluids: flow, viscosity, and pressure
• Determination of head loss in pipes by D’Arcy’s formula, use of Moody diagrams
• Immersed surfaces: centre of pressure, use of parallel axis theorem for immersed surfaces
• Hydrostatic pressure and thrust on immersed surfaces
• Relate knowledge and skills on fluid systems to operations and plant management through real-world industry scenarios.

LO4 Examine the principles of heat transfer in industrial applications

Heat transfer:

• Modes of transmission of heat: conduction, convection, and radiation
• Heat transfer through composite walls; use of U and k values; example case studies
• Recuperator, regenerator, and evaporative heat exchangers
• Application of formulae to heat exchangers
• Heat losses in thick and thin-walled pipes: optimum lagging thickness.

Case studies:

• Example industry applications (e.g., applications relevant to management of abnormal conditions, emergency management and recovery).
