The hot water coming out of a hydrothermal vent is sometimes called vent fluid. Why would you and I find these vent fluids to be an unpleasant thing to be exposed to? a They are some of the coldest fluids on Earth, being much colder than the normal freezing point of water. b They can be up to 400 degrees Celsius, and contain dissolved compounds like hydrogen sulfide, carbon dioxide, and methane. c The vent fluids are actually an exotic type of magma, made of silicate minerals. d They are actually ultra-pure water, with nothing at all dissolved in them; so pure that even simple cells will die due to the lack of nutrients in the fluids.

A rotating viscometer consists of two concentric cylinders—a stationary inner cyliner of radius Ri and an outer cylinder of inside radius Ro rotating at angular velocity (rotation rate) ?o. In the tiny gap between the two cylinders is the fluid whose viscosity (? ) is to be measured. The length of the cylinders in Fig is L. L is large such that end effects are negligible (we can treat this as a two-dimensional problem). Torque (T) is required to rotate the inner cylinder at constant speed. Showing all your work and algebra, generate an approximate expression of T as a function of the other variables.
