Asimply supported 25-foot long w33x141 beam (fy = 50ksi) supports a uniformly distributed service load. if the live load is twice the dead load, what is the maximum total service load that can be supported. don’t forget to factor in self weight. you can assume that the beam is compact and that it has continuous lateral support.

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]
