Atrue centrifugal casting operation is to be performed in a horizontal configuration to make cast iron pipe sections. the sections will have a length = 42.0 in, outside diameter = 8.0 in, and a wall thickness = .50 in. if the rotational speed of the pipe = 500 rev/min. will the operation be successful? hint: calculate gf using outside diameter of the pipe.

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]
