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/m-K, r = 8500 kg/m3 and cp = 320 J/kg-K and the heat transfer coefficient between the junction and the gas is h = 110 W/m2 -K. Determine how long it will take for the thermocouple to read 99 percent of the initial temperature difference
