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/mo C, r = 8500 kg/m3 and Cp = 320 J/kgo C, and the heat transfer coefficient between the junction and the gas is h = 65 W/m2oC. Determine how long it will take for the thermocouple to read 99% of the initial temperature difference
