WEEK 1

ACTIVITY 1

Category: Household

Sub-category: Air Humidifier (appliances)


First question: 

Humidifiers are devices that emit water vapor or steam to increase moisture levels in the air.

Humidifiers work according to the principle of evaporation

It consists of a motor for the air flow and a humidifier surface, which is in direct contact with water. A fan generates an airflow that applies water to the humidifier surface. The water evaporates and is transported by the air flow out of the device into the room air.

(Evaporation. Condensation. Mass transfer. Heat transfer)



Second question:

Chemical devices. Provides convenience to users and has particular chemical transformation which is from the liquid state, water, to the gaseous state, water vapor or steam. It is convenient for users as air humidifiers exist in variable sizes and have smaller ones as well, which makes it more portable, saves space in your living area while decreasing the growth of mold and mildew to avoid an abundance of dust mites.

Using the humidifier as an example it takes distilled water→water vapour→moist air

WEEK 7

HELLO 👋  WELCOME back to our blog! ! So this week we were introduced to a new software called, "Fusion 360" . This software will help us to draw and design the different components so that we can visualize better. These drawings can actually be printed out using a 3D printer if needed😲. PRE-LESSON PREPARTION💨 To get familiarized to the software we were given a task to make a keyring  🔑using this software before our actual lesson. We all had our own difficulties at first but after a while of getting used to the components, we could easily find the components during the actual online lesson.💻 Take a look at our own customized keyrings that all of us did individually. 😄👇 Figure 1 : Kalyani's keyring Figure 2 : Jolyn's keyring Figure 3 : Madelaine's keyring Figure 4 : Cui Han's keyring ACTIVITY 1😬 We were tasked to sketch constraints during lesson with the aid of our  lecturer .   It was more difficult than the keyring as it involved sketching more sha

WEEK 5 PRACTICAL 2

HELLO👋! welcome back to our blog. This week we got to do practical 2 at the comfort of our homes due to the tighter restrictions in phase 2 in Singapore. Don't worry we had taken videos and photos so that you can be on this journey with us as well😁. PRACTICAL 2 This practical is about using an airlift pump to pump water from a 5L jug to another container. We used different measurements as identified in our lab manual to see which measurement would pump the same amount of water in a shorter amount of time. We used flowrates to determine which measurement is FASTEST💨 . Higher the flowrate, the faster it takes to pump water from the jug to the other container. Safety Precautions taken❗️: 1.Do not handle the electrical plugs when hands are wet 2.Clear the working area, i.e. do not put laptop within 1 m of the working area 3.Do not place the water containers near the edges of a table to prevent them from dropping off Roles & Responsibilities Name Team Leader (Ensures all procedur

Hello👋 everyone! Welcome back to our week 5 blog. For today’s activity we will doing Material for Design. Now what is Material and Design?💭 It is a conventional and traditional method Finding a material with properties similar to a product With no manufacturing difficulties and not costly💰 The whole process is to find a better way to improve an old product.👍 CP5065 Introduction to Chemical Product Design Design for Materials – Worksheet for Activity Class: DCHE/FT/2A/02 Group: 5 Name of material Nylon Chemical Name Polyamide plastic General Description Nylon is a thermoplastic silky material, first used commercially in a nylon-bristled toothbrush in 1938 followed more famously by women’s stockings in 1940. It is composed of polyamides of high molecular weight and usually, but not always, manufactured as a fibre. General Properties -highly elastic to viscoelastic grades in a range of densities and hardness -lightweight -very strong -not expensive -quick drying abilities -lustrous Op
