A horizontal copper plate 10 cm thick is initially uniform in temperature at 250◦C. The bottom surface of the plate is insulated. The top surface is suddenly exposed to a fluid stream at 80◦C. After 6 min the surface temperature has dropped to 150◦C. Calculate the convection heat-transfer coefficient that causes this drop.

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.
