Problem 3 A portable thermocouple is used to measure the air temperature inside of a sauna. The sauna is unbearably hot and a person can only stay for 20 seconds, during which the temperature reading keeps on changing and a steady temperature is not reached. Leaving the thermocouple reader in the sauna for extended period of time has been deemed too risky for an electronics device Fortunately, a transient heat transfer model can be used to extract the temperature in...

The earth's temperature can be measured using either ground-based sensors or infrared-sensing devices mounted in aircraft or space satellites. Ground-based sensoring is very accurate but tedious, while infrared-sensoring appears to introduce a bias into the temperature readings-that is, the average temperature reading may not be equal to the average obtained by ground-based sensoring. To determine the bias, readings were obtained at five different locations using both ground- and air-based temperature sensors. The readings (in degrees Celsius) are listed here. Location...

1) A spherical aluminum ball at a uniform temperature of 250°C is dropped into an oil t(s) Tscat t(C] bath at 50°C. The ball's surface temperature is measured using a thermocouple. The 250.3 table below (also provided as a spreadsheet in a separate file) shows the recorded 10 238.1 temperature versus time every ten seconds for 300 seconds. If the Bi #<<1, the lumped capacitance solution 20 230.1 30 221.0 6h e(t) = 0,exp( 219.0 40 PCD is valid. Here,...

A group of physics students collected data from a test of the projectile motion problem that was analyzed in a previous lab exercise (L5). In their test, the students varied the angle and initial velocity Vo at which the projectile was launched, and then measured the resulting time of flight (tright). Note that tright was the dependent variable, while and Vo were independent variables. The results are listed below. (degrees) Time of Flight (s) Initial Velocity V. (m/s) 15 20...
