Hi,
As part of an experiment I am doing I have a small uniform circular disc that is submerged in 20ml of a liquid and is spinning at 2000rpm for 60 seconds. The disc is 1mm thick and 40mm in diameter. I am trying to see what effect the spinning disc has on the growth of cells that are in the liquid but I am worried that the rotation of the disc at this speed for this length of time might be causing the liquid to heat up a couple of degrees, compromising the accuracy of my results. Is there any way that I can calculate the amount of heat energy dissipated into the liquid due to the rotation of the disc?
To make it simpler, it can be assumed that the liquid has the same properties as water (density, viscosity, specific heat capacity etc.).
Any help would be hugely appreciated, I have made a stab at it but am unsure about the method.
Thanks very much!
Michael
