The lumped parameter solution for transient conduction can be conveniently stated as

t – t _a/t_I – t_a = 2 exponential (- B _I F₀) t – t _a/t_I – t_a = exponential (- B _I F₀) t – t _a/t_I – t_a = 3 exponential (- B _I F₀) t – t _a/t_I – t_a = 6 exponential (- B _I F₀)

A thermocouple junction of spherical form is to be used to measure the temperature of the gas stream. The junction is at 20 degree Celsius and is placed in a gas stream which is at 200 degree Celsius. Make calculations for junction diameter needed for the thermocouple to have thermal time constant of one second. Assume the thermos-physical properties as given below
k = 20 W/ m K
h = 350 W/m² K
c = 0.4 k J/kg K
p = 8000 kg/m³
