Human body temperature to give the most accurate assessment of core body temperature, particularly in hypothermia. In the early 2000s, ingestible thermistors in capsule form were produced, allowing the temperature inside the digestive tract to be transmitted to an external receiver; one study found that these were comparable in accuracy to rectal temperature measurement. In the 19th century, most books quoted "blood heat" as 98 °F, until a study published the mean (but not the variance) of a large sample as . Subsequently that mean was widely quoted as "37 °C or 98.4 °F" until editors realised 37 °C is closer to 98.6
Normal shock tables the tables. Next, the equation below shows the relationship between the post normal shock temperature, formula_14, and the upstream ambient temperature, formula_15. Finally, the ratio of stagnation pressures is shown below where formula_17 is the upstream stagnation pressure and formula_18 occurs after the normal shock. The ratio of stagnation temperatures remains constant across a normal shock since the process is adiabatic. Normal shock tables In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. With a given upstream Mach number, the post-shock Mach number
