Youre working on a new microrobot with the same size and shape as a 3 m long bacterium, which typically travels at speeds of 10 m/s in water ( = 0.001 kg m s-1 ). Because microfabrication for these microrobots is very expensive, you want to test cheaper larger scale models in your lab that will allow you to optimize your design. If your models are each 1.5 cm long and your pump in your test tank creates a flow of 0.1 cm/s, what is the viscosity of the fluid you should use with your model that will allow you to best replicate the ratio of forces affecting the bacteria? You can assume that you are adding a different fluid to water to modify the model fluid viscosity that does not noticeably affect the density of the fluid, where the combined solution remains Newtonian.
