How cross-sectional area affects drag on a cylinder falling through water

[tnorkhangpa]

Hi,
I am Tsering and am studying in the Mahindra UWC of India. I am doing a physics extended essay on How the cross section area of an object(cylinder) will affect the rate of slowing down of the object when dropped from a certain height into a fluid (water in my case). I will try to find the viscosity index of water and some other things as well. Can you please guide me through this things as I am not able to approach my physics teacher.
Thanks a lot.
Tsering

You'll have to be more specific. If you need help with general concepts, you should read about them in books or on the internet. We can help you with specific questions if you need.
