A) Energy cаn be created or destroyed within a control volume depending on the type of work done.B) The conservation of energy states that the sum of heat transfer and work input must equal the rate of change of total energy in the system.C) Shaft work is the only type of work considered in energy conservation equations.D) The Reynolds transport theorem does not apply to energy conservation in fluid systems.
A 1992 аrticle in the Jоurnаl оf the Americаn Medical Assоciation ("A Critical Appraisal of 98.6 Degrees F, the Upper Limit of the Normal Body Temperature, and Other Legacies of Carl Reinhold August Wunderlich") reported body temperature, gender, and heart rate for several subjects. The body temperatures for 25 female subjects follow: 97.8 97.6 97.4 97.6 97.8 97.9 98 98 97.8 98.1 98.2 98.3 98.8 98.4 97.4 98.4 98.5 98.6 98.6 98.7 98.8 98.8 98.9 98.9 99 Statistics Variable Total Count Sum Sum of Squares Body temperature 25 2456.300 241342 Use this information to construct a 96% interval estimate for the true mean female body temperature and comment on the claim that the true body temperature should be 98.6 Degrees F. You may assume that body temperatures follow an approximate normal distribution.
