I am wondering how to find the dinamic viscosity of vegetable oil.?

I think you're going to need a machine to measure it for you, something like a rotary viscometer.

This is how you do it.\nYou need to find out the mass of hexane first. Calculate the mass of hexane by subtracting the mass of empty beaker from the mass of beaker with hexane. Once you obtain the mass of hexane, divide it by the volume which is 5ml. You will get your density in units g/ml. I hope this was enough help. E-mail if you need more than this.

Dear Little Giggl:  I think the answer to your question is VELOCITY, but it is NOT viscosity - which is the RESISTANCE property in liquid, that prevents quick flowing.\n\nFlow dynamics is said to be measured according to density and pressure which help determine velocity measurement of liquid.\n\nThank you for the question. . .it helped me to learn something.

Jimbo, you gave up too soon......\n\nV = L*W*H = L*W*x in this problem\n\nV = (6-2x)*(4-2x)*x\n\nV  oila!

Use the second derivative test, not sure exactly what it is still but it should be easy to find on the internet.

I believe in a generalized fashion the equation for flow rate is:\n\nFlowrate = K*(cv)*((p)^.5)\n\nK = a variable to adjust for various fluids

The CRC Handbook of Chemistry and Physics has all kinds of good information like that (although it is pricey).\n\nOr, search the web for the specific liquid of interest.

Vegetable oil and isopropyl alcohol.  Put a little food coloring in to help differentiate between the two (it will only dissolve in the alcohol)
