Extracted text: Q1) A jacketed thermocouple initially at 20°C is immersed in boiling water. After 0.8 seconds the indicated temperature is 75°C. Later the thermocouple is removed and the indicated temperature after 1.4 seconds in air at 20°C is 60°C. Assuming that these processes can be represented as first order transfer functions calculate the time constants for indicated temperature response in boiling water and air. Why do the values in boiling water and air differ?
