For laminar free convection flow on a vertical plate, the recommended values of c and n for use in the correla- tion of equation 9.24 are 0.59 and 1/4, respectively. derive the values of c from the similarity solution, equation 9.21, for pr-0.01,1, 10, and 100.

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]
