Homework #1 Solution
Problem 1
In this problem, we are asked to consider the design of a straw by a fast-food company for a new
milkshake. We need to perform a dimensionless analysis so that there is sufficient volumetric
flow through the final product, g
Homework #2 Solution
We have a liquid with density and viscosity flowing over an inclined plane of width W. The
plane is inclined at an angle of . The flowing liquid is at steady state with some volumetric
flowrate Q and forms a liquid film with thickness
Homework #3 Solution
Following the same procedure shown in class and in section 3.2.1 of the book, we can
derive an expression relating the forces acting on the fluid in our system:
1
( ) =
Here we have also recognized that we are looking for a steady
