A very fine-grained material may have a mean grain intercept of the order of 1 micron or 10-6 m. Assuming the grain-boundary energy of the metal is 0.8 J/m2, what would be the approximate value of its grain-boundary energy per unit volume? Give you answer in both J/m3

A water drop slung onto a skillet with a temperature between 100°C and 200°C will remain a liquid for about 1 second. However, if the skillet is much hotter the drop can last several minutes. This is due to the Leidenfrost Effect, named after an early investigator (circa 1756). The longer lifetime is due to the support of a thin layer of air and water vapor that separates the drop from the metal (by a distance L, as shown in...

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC. (a) Write balanced equations for the combustion of each component of the fuel gas. (b) Explain the need for excess air....
