Homework Statement
A shearing force of 100 dynes is applied to the side of a rectangular plate of 5 x 10 cm dimensions placed on top of a 0.5 mm high column of Newtonian fluid that is initially at rest. As a result of the shearing force, the plate moves at a speed of 11.2 cm/sec. What is the viscosity of this Newtonian fluid? (5 pts)
PS: Can you guess what this fluid is?
Homework Equations
Viscosity = (Force/Area)/(Velocity/Length)
The Attempt at a Solution
Force = 100 dynes
Area= 50 cm^2
Velocity= 11.2 cm/sec
Length= .05 cm
Viscosity = (100/50)/(11.2/.05)
=(2)/(224)
=.00893 Poise
=.0000983 CeniPoise
Can someone double check my work and see if I am on the right track? I am positive I have the right inputs and the right equation, but I have a feeling I am messing up on the units because the answer seems way too low. Thanks in advance!
