Your solution MUST specify the DESIGN and Java source code implementation which satisfies the requirements above. While you may specify any number of solution design components, your overall solution design must implement the following class components and relations: Class Number (-) short int V; ( ) Number() ( ) Number(short int n) ( ) Number(Number n) ( ) set(short int v); ( ) short int get()

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]
