probe, which may be is used to through a duct. modeled as a cylindrical measure the temperature at The aveagevalue of h in the air stream A thermocouple diameter and 10 cm long, an air stream flowing along the probe is 100 W/m2°C, and k of the probe is 70 W/m°C. The wall temperature, i.e., the temperature at the base thermocouple at the end of the probe of the probe is 30°C, while the registers 95°C. i) Obtain a more nearly by accounting for heat ii) How might of error described iii) What would exchange between above case? correct value conduction along the probe. the thermocouple above? rod, 2.5 mm in the center of for the air tem[perature in the duct system be designed to minimize the type be the effect on the thermocouple error of radiation the thermocouple bead and the walls of the duct in the probe, which may be is used to through a duct. modeled as a cylindrical measure the temperature at The aveagevalue of h in the air stream A thermocouple diameter and 10 cm long, an air stream flowing along the probe is 100 W/m2°C, and k of the probe is 70 W/m°C.
