A gas at 1650C and 0.96 atm enters a plug flow reactor that converts 91% of the material. What is the amount of gas (in units of moles per liter, expressed to three decimal places) that is converted? You may assume, as a first estimate, that the behavior of the gas is ideal, the gas constant is 0.0821

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]
