Testing Objective To investigate different physical properties of different vacuum cleaners in order To deduce which vacuum is the most viable for consumer usage. The three different physical parameters to assess the effectiveness of each vacuum cleaner is the suction flow, power consumption and acoustic emission. Suction flow is the force that a vacuum exerts upon a liquid, gas or solid measured using an Anemometer in m/s. The second parameter, power consumption, refers to the power efficiency recorded using a power meter in Watts. Last but not least, acoustic emission refers to the level of sound emitted by the vacuum measured by a sound level meter in db. Testing Procedure For Suction Flow 1. 2. 3. 4.

Connect the vacuum cleaner into a power outlet and turn on the machine Place the Anemometer in front of the suction hole and turn it on Record the data in a table using the measurements (m/s) Repeat steps 1-3 3 times for each different vacuum

Power Consumption 1.Connect the power meter to the power outlet and connect the vacuum cleaner into the power meter 2. Turn on the vacuum cleaner for 30 seconds so the power meter will display voltage readings 3. Record the data in Watts after 30 seconds has passed 4. Repeat steps 1-3 3 times for each different vacuum cleaner Acoustic Emission 1. Connect the vacuum cleaner into a power outlet and turn on the machine 2. Place the sound level meter on a clamp above the vacuum and turn it on 3. Turn on the vacuum and after 30 second pass record the dB readings 4. Repeat steps 1-3 3 times for each different vacuum cleaner

Analysis of Measurements (Tables, Graphs, Error Analysis) \

Error measuring suction flow can be caused by uneven surfaces and distances between the anemometer and the vacuum. The possible percentage error can be found by: 100x(1.93-1.91)/3=0.6667%

Discussion and Results For the first parameter, suction flow, it can be seen that through the Suction Flow graph that Samsung’s vacuum had the highest suction flow averaging at 2.01 m/s. Furthermore, the runner up of the vacuum having the strongest suction flow is the Volta vacuum averaging 1.91 m/s suction flow and lastly Hoover having the lowest averaging suction flow at 1.88 m/s. For the second parameter, power consumption, it can be seen through the Power Consumption graph that the Hoover vacuum uses the least amount of power averaging 1486.33W after being on for 30 seconds. Then, it’s the Volta vacuum having the second least power consuming vacuum averaging 1515.667W. Lastly, the Samsung vacuum uses the most power as it averages 1623.33W. Thus, it can be seen that there is a direct relationship between suction flow and power consumption where the higher the power consumption the more the suction flow and vice versa. For the third and final parameter, acoustic emission, it can be seen through the Noise level graph that Samsung emits the highest level of sound averaging 34.9 dB At 60cm. Then the Volta vacuum emits the second highest level of sound averaging 34.2dB at 60cm. Lastly, the Hoover vacuum is the quietest averaging 29.8 dB at 60 cm. Conclusions In conclusion, it is evident through measuring the 3 parameters of sound, suction Flow and power consumption that the Samsung vacuum is the most effective vacuum cleaner having the strong suction flow however, at the cost of having a higher power consumption and higher acoustic emission than a typical vacuum. Although the Samsung is the most effective vacuum, other factors such as cost and Being made by environmentally friendly materials has a significant impact on deciding which vacuum is the most viable for consumer usage.
