After conducting experiments in the Unit Operations Lab, a strange looking liquid was found in a beaker by the cleanup team. Being Engineering students, they took the fluid into the lab to an used the Brookfield viscometer to obtain the following shear stress- shear rate data:

y (s-1 ) 5 10 20 30 40 50 60 80 100

t (Pa) 32 75 171 278 393 513 639 903 1181

1)What type of fluid is this?

2) Determine the rheological parameters for this fluid.
