1.40 Over a limited temperature range, the relation between electrical resistance R and temperature T for a resistance tem- perature detector is R = Ro[1 + a(T-To)] where R, is the resistance, in ohms (), measured at reference temperature To (in °C) and a is a material constant with units of (C). The following data are obtained for a particular re- sistance thermometer: Test 1 (To) Test 2 T (°C) 0 91 R (1) (R₂) 51.39 51.72 What temperature would correspond to a resistance of 51.47 on this thermometer?
