Based on expected flame temperature range: 600 ~ 750oC (1000 ~ 1400o F), what types of thermocouple can we use? Use room temperature (23oC) as reference, find the reference temperature voltage correction factor from the corresponding TC tables. Determine the reference
corrected, expected TC voltage output for a temperature of 745oC.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
