Water at a temperature of 80°C flows parallel to a 200 mm long flat plate with a far-field velocity of 20 cm/s. The surface of the plate is at a uniform temperature of 0°C. At a distance of 85 mm from the leading edge of the plate a miniature thermocouple is attached to the surface, with the purpose of measuring the surface temperature. The thermocouple can be idealized as a hemisphere with a radius of 0.5 mm. Calculate the maximum error in the temperature measured by the thermocouple that results from the difference between the surface temperature and the temperature of the fluid surrounding the thermocouple. Discuss the relevance of your calculation to practical measurements.
