Evaporating sweat cools the body because evaporation is endothermic and absorbs 2.44 kJ per gram of water evaporated. Estimate the mass of water that must evaporate from the skin to cool a body by \(0.50\ ^{\circ}\mathrm{C}\), if the mass of the body is 95 kg and its heat capacity is \(4.0\mathrm{\ J

In an experiment to measure the lifetimes of parts manufactured from a certain aluminum alloy, 73 parts were loaded cyclically until failure. The mean number of kilocycles to failure was 783, and the standard deviation was 120. Let ? represent the mean number of kilocycles to failure for parts of thi

Five percent excess air is used in burning the reformer fuel; it is drawn into the system at 30C and 70% relative humidity. Estimate the average molecular weight of the air. Why does it differ from the value of 29 determined in Example 3.3-4 even though the ratio of nitrogen to oxygen is the same? De
