# Unit information: Thermodynamics I in 2019/20

Please note: Due to alternative arrangements for teaching and assessment in place from 18 March 2020 to mitigate against the restrictions in place due to COVID-19, information shown for 2019/20 may not always be accurate.

Please note: you are viewing unit and programme information for a past academic year. Please see the current academic year for up to date information.

Unit name Thermodynamics I MENG11202 10 C/4 Teaching Block 1 (weeks 1 - 12) Dr. Tierney Not open None None Department of Mechanical Engineering Faculty of Engineering

## Description

Introduces first and second laws of thermodynamics to engines, machines and plant components (e.g cylinders and pistons, throttles, turbines, compressors, Otto, Diesel and gas cycles).

Aims:

To provide an understanding of terms (e.g. “reversible”, “control volume”, “enthalpy”), principles (1st/ 2nd law), and use of principles in analysis of equipment and machines.

A full syllabus is available on the Blackboard site for the unit

## Intended learning outcomes

Intended learning outcomes are linked to the six major categories of cognitive domain in Bloom’s taxonomy, and to the serial numbers for ILO’s specified by an accrediting body ( I. Mech. E. , AHEP3/ OSV5)

Successful students should be able to:

ILO 1: List the important definitions and laws of thermodynamics (knowledge, exam, OSV5-SM1b)

ILO 2: Explain the derivations of key equations and corollaries - internal energy as the first corollary of the first law, the four forms of moving boundary work, the steady-flow energy equation, the first three corollaries of the second law (comprehension, exam, OSV5-SM1b)

ILO 3: Use the concept of entropy to execute calculations giving the maximum possible efficiency of engine cycles (application, exam, OSV5-SM2i)

ILO 4: Interpret problems related to piston-cylinders, compressors, turbines and engines, said problems having aspects previously unseen in tutorial questions or past examinations (comprehension, exam, OSV5-EA1b, EA2)

ILO 5: Infer and list the assumptions and physical principles pertinent to ILO4 (Knowledge, comprehension, exam, OSV5-EA1B, EA2)

ILO 6: Construct diagrams showing plant and thermodynamics paths pertinent to ILO 4 (synthesis, exam, OSV5-EA2)

ILO 7: Execute calculations to get estimates of heat addition, work addition, cycle efficiency pertinent to ILO 4 (application, exam, OSV5-SM2i, EA1b, EA2)

ILO 8: Carry out, on working machinery, measurements of thermodynamic and mechanical properties appropriate to the evaluation of efficiency (application, laboratory, OSV5-P3)
