Week 5 (P2)

Assigned roles Questions and Tasks 1. Plot tube length X versus pump flow rate. (X is the distance from the surface of the water to the tip of the air outlet tube). Draw at least one conclusion from the graph. 2. Plot tube length Y versus pump flow rate. (Y is the distance from the surface of the water to the tip of the U-shape tube that is submerged in water). Draw at least one conclusion from the graph. 3. Summarise the learning, observations and reflection in about 150 to 200 words. The team have observed that placement of the rubber tubing and u-tube played an important role in the water flow rate. At first we could not even get the water out of the u-tube as the flow rate was too low to exit the u-tube. After thinking, we increased the water level in my pail as we thought that b was way too high for a low water level. At first, we thought that the pump was too weak, however at the end of the experiment, the water level in the pail should also be taken no...

Week 5 (Design for Materials)

  CP5065 Introduction to Chemical Product Design Design for Materials – Worksheet for Activity Class DCHE/2A/01 Group: 1     Name of material Recycled PE   Chemical Name Polyethylene   General Description Recycling has become popular in today’s world, especially when it comes to plastic. Instead of using up fossil fuels which are finite sources, recycling plastics are much more efficient. It gives more purpose to these non-biodegradable materials rather than just throwing it out after one use. This benefits the environment as it reduces the carbon footprint when recycling plastic instead of producing new plastic. Such companies that recycle plastic like Parley in particular, collects plastic waste found in oceans and give those plastics a new life . Recently, Parley has collaborated with Adidas to create new function...

Reflection We chose the most feasible and suitable material with COWS Matrix. COWS is an acronym for criteria, options, weightage and score. We selected criterias based on the application of the material. Such examples are tensile strength, if the material is carcinogenic, flexibility, etc. The weightages shall then be given to the criteria based on its importance depending on the application of the material, this also plays a huge role in giving scores to find out which material is the most suitable. Scores will be usually given from 1-3 with 1 being the worst and 3 being the best. The most suitable material will be identified by having the highest score. Group Assignment Our group have been tasked to select materials for a single use (disposable) water bottle that does minimal environmental harm. Step 1: List the material requirements for the design The first requirement is corrosion resistant. This prevents the material from corroding and contaminating the water when it...

  Reflection In Week 3's lesson, we have learnt how to use an acronym called SCAMPER , which are different types of ideas to improve an innovation that may make it multi-functional rather than just having one purpose. S - Stands for SUBSTITUTE where certain parts of the device could be replaced with a much more advanced or a better alternative. C- Stands for COMBINE where two or more ideas can be merged together so that the device could be multi-functional. A - Stands for ADAPT where the product can be used for another problem. M - Stands for MODIFY where a part of the device could be adjusted and changed to a better version. P - Stands for PUT TO ANOTHER USE where our current ideas could be used as another solution for a different situation. E - Stands for ELIMINATE where some parts can be eliminated in order to simplify the product. R - Stands for REVERSE where the product gives off a solution that opposes our intended purpose. Besides learning how to use SCAMPER, we also rev...
