Attached is the data you need to do the extrusion lab. There are two pages to the .pdf. Please follow the lab report instructions to do the calculations, analysis, etc. Also, adhere to the size and font specified.

Thanks, Jessica

To do the lab write-up calculations, you will need the following information: the extruder screw is 18 inches long and 3/4 of an inch in diameter.

Since I am getting this to you late, I combined the two homeworks into 1 which is due Fri the 6th.

There will be no lab class tomorrow. The extrusion lab has been postponed to March 11th. Class will still meet tomorrow in the MSE conference room at noon.

The entire lab should be at least two and no more than three pages long. Make sure that you have section headings in your lab report such as: experimental, results, and conclusion. These headings can be bold faced and placed on the same line as other text to save room. This time integrate your plots and graphs within the text. Do not use a cover sheet.

The focus, ie, most of your grade, for this lab write-up should include: (1) following the steps clearly outlined on pages 118 and 119 of the lab handout that you received. Include a chart, plot of all data, and make sure that whatever units you choose to use are labeled correctly. (2) Explain why the viscosity readings for the two polymers were different. Saying that they are two different polymers with different properties is not enough. Specifically what is different about them that would lead to one taking so much longer to pass through the ubbelohde?

 Extra points if you know how much an ubbelohde costs, cite your source for this info.
