Two copper-constantan thermocouples with 1132 and 1116 in
Chapter , Problem 11.12(choose chapter or problem)
Two copper-constantan thermocouples with 1132 and 1116 in diameters are dipped into ice water from ambient (75F). The heat-transfer coefficient to the thermocouples is 1,500 Btu/h.ft2F. Determine the output from each thermocouple in 1,5 and 10 s. Estimate the time beyond which they will read the same temperature (within 0.1 F). Assume the properties of copper-constantan to be the same as those of copper and assume that the junction is spherical.
