You recently connected two Catalyst 2960 access-layer switches, SwitchA and SwitchB, and an external router to your network. Now you need to use the external router for a router-on-a-stick configuration for inter-VLAN routing between VLANs 2 and 4. Both VLANs are already configured on SwitchA and SwitchB and have interfaces assigned to the respective VLANs.

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]
