2. Design a no quick return four-bar mechanism to provide 50o. The rocker is 2 in. and the coupler is 4 in. Complete your drawing to clearly show the links with the different extreme positions. Write down the dimensions of each link and check for Grashof.

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]
