Athermocouple (0-200°c) is used to measure temperature in a slow-moving gas with a sensitivity of 0.05 v/°c. if you are asked to choose an a/d converter which has a range of 0-10v, determine (a) the minimum bit of the a/d converter, thus the minimum detectable temperature change of 0.1 °c, and (b) the binary code, the corresponding digital voltage, and temperature readout if the gas temperature is 150 °c,

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]
