During heavy exercise, the body pumps 2.00 L of blood per minute to the surface, where it is cooled by 2.00C. What is the rate of heat transfer from this forced convection alone, assuming blood has the same specific heat as water and its density is 1050kg/m3 ?
The thermal conductivities of human tissues vary greatly. Fat and skin have conductivities of about 0.20 W/m K and 0.020 W/m K, respectively, while other tissues inside the body have conductivities of about 0.50 W/m K.

One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose a single-story cubical house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, by what percentage would the heating cost of the house drop? Take the house to have dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors, and assume that the interior is uniformly at one temperature and the exterior is uniformly at another.
A metal rod is 10 cm long and has a diameter of 2 cm one end is in contact with steam at 100 deg C while the other end contacts a block of ice at 0 deg C. The cylindrical surface of the rod is carefully insulated so heat flows only from one end to end. In a time of 20 minutes, 320 grams of ice melts. What is the thermal conductivity of the metal?
A copper bar of thermal conductivity 401 W/(m·K) has one end at 114°C and the other end at 24.0°C. The length of the bar is 0.180 m, and the cross-sectional area is 1.00 × 10−6 m2.
