Week 1 Activity 1

 Product: Portable Bluetooth Speaker

Chemical engineering terminology: Starting from the phone, the phone transmits radio waves in the form of Bluetooth, which transmits it to a transmitter in the speaker. The transmitter then receives the Bluetooth signal and converts chemical energy stored in the battery into an electrical signal. The electrical signal is then converted to kinetic energy by magnetizing the electromagnet which causes the voice coil to vibrate. The voice coil will then vibrate the air molecules, creating sound waves.

Category: chemical devices. The Bluetooth speaker is small in size and thus it is portable. It does not require a wire connection thus it provides convenience to the user.

 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.       ...

Week 4 Activity

  Roy, Nigel ,Bjorn, Vernon Group 3 DCHE2A02 Topic: Material Selection for Inner Layer of Thermoflask For week 4, we went to revisit our last year module which was the materials for design and we were tasked to find the right material for the inner layer of a thermoflask. In materials for design, we needed to find the right requirements for the material and from there find different suitable materials. We then use the COWS matrix (Criteria, Options, Weightage and Score) to determine the best material. Here is our findings. Material Requirements In order for the liquid inside the thermoflask to remain hot/cold, the inner layer of the thermoflask must reduce the amount of heat transfer from the liquid to the surrounding. The inner layer thus should have a low thermal conductivity and a high melting point.   Since the inner layer will be in contact with water, it must resist corrosion by any liquid put into it, water and acids from soda drinks. It will be used for drinking, so i...

Week 1 Group Retreat Activity

 Firstly, we went to buy drinks as we were feeling very thirsty and while drinking we were chatting about the stuff we did during the holidays.  After finishing our drinks, we had to use the toilet. We also decided to prank Vernon by taking a wefie with him using the toilet. We were feeling stressed due to the long and hectic day and decided that we needed to distress by playing some mobile games together. We were feeling restless, so we decided to do some pushups together. Despite it being tiring, all of us had plenty of fun together. All in all, this was a fun bonding experience for our group and we felt that this opportunity allowed us to get to know one another better.
