A 0.8 mm diameter nickel- alumel thermocouple is used to measure the ...

Given, d = 0.8mm, h = 500W/mK,C = 350J/kgK, ρ = 9500Kg/m³

The sensitivity of the thermocouple is the time required by a thermocouple to reach 63.2% of the initial temperature difference. I.e.,

T−T∞ = 0.632(T0 − T∞)(1)

Using Lumped capacity method, T − T∞ = (T₀−T_∞)e(−hA/ρCV)t

From (i) 0.632 (T_o−T_∞) = (T_o−T_∞)e^{(−hA/ρcv)t}

From (ii) 0.752t = 0.4588

t = 0.61s
