[Video opens with Dr. Mathews standing with viscometer.]
Dr. Mathews: This is a Saybolt Viscometer. There are an awful large number of ways to measure viscosity. This is perhaps one of the simplest. I am going to pour this into a heated reservoir.
[Dr. Mathews pours a beaker of Pennsylvania Crude Oil into the machine.]
Dr. Mathews: And do the same with the other crude oil.
[Dr. Mathews pours a beaker of Gulf of Mexico crude oil into the machine.]
Dr. Mathews: The reason the reservoir is heated is because temperature is a factor that influences viscosity. And now I am going to do a very simple experiment. What I am going to do is yank these chains and we are going to see how long of a time difference it is between the Pennsylvania crude on the left and the Gulf of Mexico crude on the right, to see how much more viscous the Gulf of Mexico crude is. So here we go.
[Dr. Mathews pulls two chains which allow the oil to flow through the machine and starts a timer.]
Dr. Mathews: As you can see the Pennsylvania crude oil, the higher quality crude oil, the old deep crude oil, is flowing out very rapidly. There is the same quantity in each reservoir and they are at the same temperature. Where as the Gulf of Mexico, the blacker of the crude oils, is taking much longer to come out. Again, a very easy determination of the quality of the crude oil is the viscosity.
[The Pennsylvania crude oil has finished flowing out of the machine.]
Forty-two seconds for the Pennsylvania crude, and we are going to be here for a while for the Gulf of Mexico.
[The Jeopardy theme plays as we wait for the Gulf of Mexico crude to finish flowing out. Dr. Mathews shows the stop watch every once in a while. It ends at three minutes and seventeen seconds.]
