1. Falling Needle Viscometer (20 Points)
You can find information on the application of this idea in practice. Among the information supplied is that the instrument marketed can be used to measure viscosities from 1 to 108 cP. Based on the analytical solution and the fact that realistically we can measure velocities only within a certain range corresponding to falling needle times between macroscopically well identifiable points ranging from a few seconds to perhaps tens of minutes can you come up with estimates on the geometrical parameters involved that are consistent to those claims? How many different needles you feel are realistically required for that purpose? In providing your answers also note that the required experimental fluid is less than 4.5 ml.
