Determine how long it will take for the thermocouple to read 99% of the initial temperature difference.
The temperature of a gas stream is to be measured by a thermocouple whose junction can be approximated to a 1·2 mm-diameter sphere. The properties of the junction are: J/kgK,320andkg/m8500, W/mK353pCk. The heat transfer coefficient between the junction and the gas is W/m²K65 h10. Determine how long it will take for the thermocouple to read […]
