TOTAL STUDENT WORKLOAD
Students are required to attend and participate in all the formal timetabled sessions for
the unit. Students are also expected to manage their directed learning and independent
study in support of the unit.
re normal timetabled sessions do not take place, additional directed learning may be
provided, and/or students are expected to undertake additional independent learning.
A course of study equivalent to Mathematics Level 4.
This unit provides the basic principles of thermodynamics, and deals with the generation
of heat, the transfer of heat and the laws of transformation of heat into other forms of
energy. The needs of modern sea transport have given rise to complex marine
plant, such as turbines, compressors, reciprocating engines, boilers, condensers,
refrigerators and heat pumps. Each of these items makes use of the behaviour of a fluid as
it is heated, cooled and expanded, and compressed. The design and energy e
operation of such plant requires an understanding of the energy laws.
Knowledge and Understanding
Explain the principles and concepts used to analyse thermodynamic systems and
riate methods to determine the engineering efficacy of thermodynamic
systems and processes.
Practical and Professional Skills
Apply the theory of thermodynamics to practical marine engineering applications.
Transferable and Key Skills
te effectively by means of written reports and problem solutions.

LEARNING AND TEACHING STRATEGY
A series of structured lectures introduce the theoretical concepts of the unit. This is
complemented by the use of a series of tutorial sheets in smal
l group sessions to apply the
theory to problem solving, allowing students to identify solutions to thermodynamic
systems and processes.
closed book examination
In order to assist the students learning, the coursework assessment process is designed to
ack of a regular and formative nature. The tutorial sheets, used in the small
group teaching sessions, and the coursewo
rk assignment (AE2
) both provide opportunities
for formative feedback. The assignment is designed to assess learning outcomes 3 and 4,
nd the examination, learning outcomes 1 and 2.
Aggregation & Re
No departure from standard University regulations.
