A thermocouple at 20 °C is suddenly placed into a 60 °C water bath. The thermocouple is covered by a brass sphere that is 10 mm in diameter. The density of brass is 8500 kg/m3 and the specific heat is 0.385 kJ/kg-°C. The heat transfer coefficient is determined to be 1900 W/m2 °C. Determine the time constant.
