A cubical piece of heat-shield-tile from the space shuttle measures 0.11 m on a side and has a thernal conductivity of 0.065 J/(s m C°). The outer surface of the tile is heated to a temperature of 1,339°C, while the inner surface is maintained at a temperature of 24°C.

(a) How much heat flows from the outer to the inner surface of the tile in 7 minutes?

(b) If this amount of heat were transferred to 3.8 litres (3.3 kg) of liquid water, by how many Celsius degrees would the temperature of the water rise?

Take cwater = 4186 J/kg

A 12 meter long and 12 mm inner diameter smooth pipe is used to heat a liquid in an industrial process. The liquid enters the pipe at a temperature of 25o C and a mean velocity of 0.80 m/s. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the pipe so that the fluid exits at 75o C. The fluid average properties are ? = 1000 kg/m3 , Cp = 4000 J/kg·K,...

Temperatures of gases inside the combustion chamber of a four-stroke automobile engine can reach up to 1000°C. To remove this enormous amount of heat, the engine utilizes a closed liquid-cooled system which relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder. Assume you have a 6-cylinder engine, and each cylinder has a diameter of 9.00 cm and height of 11.6 cm...
