Q1: [05] It is known for a K-type thermocouple that thermoelectric voltage at 50 °C and 500 °C are 2.023 mV and 20.644 mV, respectively when the reference junction is kept at 0 °C. Thermoelectric voltage versus temperature relation is approximated as, Et,0 = a × t + b * t2. For a certain temperature (t1) of the hot junction, the thermocouple shows 10 mV, with the reference junction at 20 °C. Find the unknown temperature ti of the hot junction using the laws of thermocouples (state the law when applying).
