A) \[560{}^\circ C\]
B) \[520{}^\circ C\]
C) \[540{}^\circ C\]
D) \[500{}^\circ C\]
Correct Answer: B
Solution :
: In a thermocouple, \[{{T}_{n}}=\frac{{{T}_{c}}-{{T}_{i}}}{2}\] where\[{{T}_{i}}=\]temperature of inversion. \[270=\frac{20+{{T}_{i}}}{2}\] or \[{{T}_{i}}=540-20=520{}^\circ C.\]You need to login to perform this action.
