Prototype A

Learning Outcome 4. Design and produce a product/process/system that offers a practical solution to the problem, including all details necessary to bring the design to fruition.

Powder Dispenser (Prototype A)

We have done the test to find out the volume of the 403 powder we needed for specific consistencies as shown below in the table, which are the amount of powders we need for a certain job when we are building a boat.

West system 403	Weight (g)	Density (g/ml)	Volume (ml)
Ketchup	3	0.111 g/ml	27.027 ml
Mayonnaise	5	0.111 g/ml	45.045 ml
Peanut Butter	11	0.111 g/ml	99.099 ml

From the test, we have measured the weight of the powders and then calculated the volume of each consistency Ketchup, Mayonnaise and Peanut Butter. The next step was to produce the tubes for each consistency with the right size by the volume. We have found some materials from our workshop which were the PVC tube as shown the photo right.

However, we are looking for tubes that we can see inside the tube. As shown in the photo right, we have made the tool that we can dispense the powders effectively. We need the tube something similar to the one showing in the photos.

Therefore, we have researched the more tube that is more clear. The supplier and the price and other details will be shown below in the table.
