Subject: HWK 4 Dynamic light scattering data on line

Dear ChE 530 students,

The data for the dynamic light scattering problem should be on-line momentarily. The other required properties are

laser wavelength = 514.5 nm

solvent viscosity (eta) = 0.89 cP

solvent index of refraction n = 1.411

To import the data into excel, look for a command such as

Data --> Get external data --> import text file

I will not be on campus on Friday, but I will see email if you have a question.

Prof. Greenfield
