Question

The temperature of a flowing gas stream is measured using a thermocouple, which is a
spherical metal bead 1.5 mm in diameter. The properties of the metal are p =9000 kg/m
Cp = 550 J/kgK and k=30 W/m.K. The film coefficient between the gas and the metal
is 410 W/m.K. If the gas temperature is suddenly increased from 300 °C to 310 C,
how long will it take for the thermocouple to reach 308 C?​
