Prep-Task | 10 | 6 | Some possible confusion about the retention of solute in reverse osmosis | |
Presentation | 5 | 3 | Some deviations from impersonal nature of reporting at several points | |
Abstract | 5 | 3 | No statement of outcome of major objectives | |
Procedure | 5 | 2 | system diagram but missing conductivity probes in tank and pressure control line No statement about reducing pressures back from 60 bar | |
Results | 5 | 2 | missing comment on errors and no references to diagrams (graphs) of the nature of the flux vs pressure relationships also missing sample calculations | |
Discussion | 5 | 3 | No discussion of the oemotic pressure or. No discussion of error | |
Conclusions | 5 | 2 | No improvements suggested .. No statement of the linear nature of the relationship between pressure & flux | |

General comments | Good try at report – but many mistakes and omissions outlined above mean that there is much in room for improvements if comments are acted upon. (p/s: baik dia ni, sbb bagi smgt nak buat lab report, die puji dulu baru comment. hehe.) | |||
Procedure/apparatus - Include a description of the apparatus and write in past tense and in paragraphs.
Abstract - Inlcude a more detailed consideratio of results/differences, need to be clear.
Results - Sample calculation for heat flux missing. Not sure how you got your values from the graph for ZT calculations, approximately 101 kN/m2 should have been added to gauge pressure to get absolute. Watch units in calculations, latent heat of evaporation should have been in J/Kg.
Discussion - Make sure your points of discussion are clear. I wasn't sure what you were trying to say.
Conclusion - Include clear ideas from improvement to experiment and apparatus.
both lab report I managed to get 52.5% and 53.44% respectively. Tahap 50% je marks lab report yg telah dibuat oleh adilah mustafa. Namun begitu, ADA lah peningkatan abt 1% pun da buat kite happy sikit.hihihi.
yeah,its snowing*.* Alhamdulillah,Snow before this da kene hanyut dgn hujan2 di Glasgow. and now its snowing again here in Glasgow. Im Happy!
