1. The problem statement, all variables and given/known data A flat plate viscometer consists of a disc of diameter 50mm rotating at 300rpm in close proximity to a fixed horizontal plate. When the gap between the plates is 0.1mm, it is found that the torque required to drive the disc is 0.2Nm. What is the viscosity of the liquid between the plates? 3. The attempt at a solution First I found the angular velocity to be 31.41 rad/sec, and then used U=rw to find the constant velocity (r=radius, w=angular velocity) Next i used [tex]\tau = \mu(U/t)[/tex], knowing the torque, velocity and gap thickness to give me the viscosity [tex]\mu[/tex] Does this look somewhat right?
