Question Solved1 Answer Q.3 A thermocouple with a 1.5 mm diameter spherical bead is used as a temperature sensor to measure air flowing in a wind tunnel duct and has a time constant of 1 seconds. It is required that the sensor have a 90% response time of less than 1 sec. Determine if this sensor meets this requirement? If not what should be the time constant required to meet this Q.3 A thermocouple with a 1.5 mm diameter spherical bead is used as a temperature sensor to measure air flowing in a wind tunnel duct and has a time constant of 1 seconds. It is required that the sensor have a 90% response time of less than 1 sec. Determine if this sensor meets this requirement? If not what should be the time constant required to meet this requirement and size of the thermocouple bead? (35 pts)
