Use the following two viscosity values for liquid water:
η = 1.8 x 103 Ns/m2 at 0 o C
η = 2.8 x 104 Ns/m2 at 100 o C
At what temperature do you need a lesser force to pull a given glass slide with a given speed v though the water?

viscosity is a measure of the force it takes to move through the liquid
the lower value requires less force.
