Find the neutral and inversion temperatu...

Find the neutral and inversion temperatures for `Ni-Cu` thermocople with the cold junction at `0^@C`. Use data from previous example.

Text Solution

Verified by Experts

The neutral temperature is `theta_n = - alpha/b`
`= (16.3 xx 10^(-6))/(0.042 xx 10^(-6)) ^@ C = 388^@ C`
The inversion temperature is double the neutral temperature, i.e., `776^@ C`.
