Draw the microstructure you would expect at room temperature if this 0.5 wt% C binary Fe-C alloy were slowly cooled to room temperature from 1100 C. Clearly label all phases in your drawing. Make sure you clearly indicate the eutectoid and proeutectoid phases. You only need to draw one microstructure at room temperature.

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]
