The temperature of a gas stream is to be measured by a thermocouple whose junction can be approximated as a 1.2-mm-diameter sphere. the properties of the junction are k = 35 w/mâ‹…k, rho = 8500 kg/m3, and cp = 320 j/kgâ‹…k, and the heat transfer coefficient between the junction and the gas is h = 110 w/m2â‹…k. determine how long it will take for the thermocouple to read 98.5 percent of the initial temperature difference
