Which relationship was characterized in the "Shapes and Fluid Forces" lab?

mass and fluid drag

surface area and fluid drag

size and fluid drag

C. surface area and fluid drag

Explanation:

Surface area is not important when one is dealing with pressure drag, but it is important when dealing with viscous drag — drag caused by layers of the fluid sticking to the object and to one another. More surface area means more of the object is in contact with the fluid, which means more drag.
