  Chemical Product: Cooling Backpack. The majority of the backpack will be made of plastic for the backpack casing, cooling components and cooling tubes. Stage 1 - Raw Materials or Extraction Main material of our chemical product is plastic which is derived from crude oil. Crude oil is extracted from underground reservoirs using traditional drilling and pumping methods. Stage 2 - Manufacturing and Production The distillation of the crude oil is carried out. Naphtha which is extracted from the crude oil is then mainly used for the production of plastics. Polymerisation and polycondensation are then the 2 main processes used to convert naphtha into plastics. The plastic is then molded into the desired product shape and is then packed  C2C Principles: Use of Renewable Energy - The machineries can be operated by solar power instead of using electricity generated from burning fossil fuels. Stage 3 - Packaging The product is wrapped in plastic and stored in cardboard boxes. Bubble w...

 Hello peeps. This week we carried out an experiment we were assigned called the air-lift pump challenge. we were required to contract the set up with provided equipment.  Here is our equipment and experimental setup  Here are the results we obtained from the experiment Experiment 1 b = 10cm, Y=16.5cm a (cm) X (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 2 14.5 5.93 5.80 5.71 5.81 4 12.5 4.20 4.13 4.23 4.19 6 10.5 2.82 2.63 2.60 2.68 8 8.5 1.39 1.11 1.93 1.47 10 6.5 0.39 0.37 0.39 0.49 Experiment 2 a = 2cm, X=14.5 b (cm) Y (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 10* 16.5 5.93 5.80 5.71 5.81 12 14.5 2.89 3.78 3.20 3.29 14 12.5 1.35 1.35 1.20 1.3 16 10.5 0.19 0.19 0.18 0.19 18 8.5 0 0 0 0 20 6.5 0 0 0 0 we used an estimated flowrate of 0 as t water was barely being pumped out. it took too long to collect 100ml of water and it was not feasible for the experimenter to hold the tube for so long. 1.       ...

 For week 5, we were tasked to find a material that appeals to the group and discuss on this material can be replaced with something in an existing product and how changing the design will enhance the functionality of the product. Here is what our team discussed.  Class: DCHE/FT/2A/02 Group: 3 Name of material PORON® Chemical Name NA (Mixture of Polyurethane Foam, Alumina Trihydrate, Titanium Oxide, Carbon Black, Fused Silica and PET) General Description PORON® foam is a cellular urethane which offers long lasting cushioning in a material for the first use and throughout the life of a product. Lightweight, flexible and with a breathable layer that draws water vapour and perspiration away this high density the material has been used in a wide variety of applications from insoles and sock liners to bag strap padding and many others. The material can be formulated in a wide variety of firmnesses and densities and is supplied in continuous rolls which can be easily fabricated:...
