5. It is required to design a resistance thermometer (RTD) using a nickel alloy wire of 0.02 mm (2 marks) OUTM UTM a. Calculate the length of the wire should be? UTM diameter. The thermometer resistance at o°C is to be 100 0. Take for nickel value of resistivity, p, as 8.7 x 10° a cm at 0°C and the temperature coefficient of resistance, a, 0.0068 °c. (1 mark) OUT b. Determine the value of resistance at steam point. U
