Question

A balloon as in Figure 2, carrying a first-order temperature sensor, rises through the atmosphere at a speed of 6m/s. Assume the temperature varies with the altitude at 0.15 °C/30m. The balloon radios temperature and altitude readings back to the ground Determine the transfer function for the temperature sensor and define its parameters. (5) a. A zero temperature (0 C) is expected at an altitude of 2910 m; however, the balloon reads this at an altitude (5) c. If the above sensor is used to measure a periodic signal with a frequency of 0.08rad/s, what would be the (5) d. If the temperature sensor reads within a frequency constant of 0.025 rad/s, what percentage error do you (5) b. of 3000m. What is the time constant for this sensor? time delay? expect in your reading? Balloon Going Up Temperature transducer Altitude Ground Figure2
