 PE3001 Applied Thermodynamics & Fluid Mechanics:                                             In attempting to achieve these learning outcomes I plan to employ a range of teaching techniques
 This is a third year module on the BE degree in Process & Chemical                           including lectures, videos as well as practicals, lab sessions and relevant props (Table 1).
 Engineering course which I have taught and developed over the past 7 years.
 It deals primarily with fluid mechanics and applied thermodynamics for                           Table 1 Teaching strategies employed            Lect e.g.      Vid      Prop     Lab

 the past 7 years, I felt I was quite happy with the module as my most ‘mature’                   Estimating Pressure drop in:
 module. This sense was reinforced by generally very positive formal feedback                       Newtonian Pipe Flow (Lam./Turb.)              ☺       ☺      ☺                 ☺
 from the module participants. Indeed the approach I had increasingly taken                       [2,3]
 was in fact towards what I viewed as a very practical approach to fluid                            Networked or branched flow [4]                ☺       ☺

 to describe fluid systems and hence employ these to design system through
 estimating pipeline pressure drops, flowrates and by selecting appropriate                         Multiphase flow [7]                           ☺       ☺      ☺                 ☺

 an outcomes driven model. Nevertheless, I felt that by applying a systematic                     [8,9,10,11,13]
 learning outcomes approach to this module, I could take my teaching and the                      Design of pump-pipeline systems [12,14]         ☺       ☺
 students learning to another (higher) level and thus further improve the                         Navier-Stokes equations [15,16]                 ☺       ☺      ☺
