You need to precisely measure the dimensions of a large wood panel for a construction project. Your metal tape measure was left outside for hours in the sun on a hot summer day, and now the tape is so hot it’s painful to pick up. How will your measurements differ from those taken by your coworker, whose tape stayed in the shade? Explain.

A certain material has a thickness of 30 cm and a thermal conductivity of 0.04 W/m・ ◦C. At a particular instant in time, the temperature distribution with x, the distance from the left face, is T =150x2 −30x, where x is in meters. Calculate the heat-flow rates at x = 15 cm.
An engineer who is working on the heat transfer analysis of a house in English units needs the convection heat transfer coefficient on the outer surface of the house. But the only value he can find from his handbooks is 22 W/m2·K, which is in SI units. The engineer does not have a direct conversion factor between the two unit systems for the convection heat transfer coefficient. Using the conversion factors between W and Btu/h, m and ft, and °C and °F, express the given convection heat transfer coefficient in Btu/h·ft2·°F.
