Aculvert passes under a temporary access road but any excess water not passing under must go over the road. the culvert pond depth upstream of the road is 905, but the road crown is set at 904. how much water will over-top the roadway? assume the roadway section being overtopped is 110 feet and that the weir coefficient for the roadway is 3.2.

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]
