A chromel-constantan thermocouple measuring the temperature of a fluid is
connected by mistake with copper-constantan extension leads (such that the two
constantan wires are connected and the copper extension lead wire is connected to
the chromel thermocouple wire). If the fluid temperature was actually 250C and the
junction between the thermocouple and extension leads was at 90C, what emf
would be measured at the open ends of the extension leads if the reference junction
is maintained at 0C? What fluid temperature would be deduced from this
(assuming that the connection error was not known)?
