Calculate the maximum Dead Load Deflection, Live Load Deflection and Long Term Deflection for the simply supported beam below. The dead load including its own weight is 1 k/ft. The live load is 0.7 k/ft. Assume 30% sustained live load for 3 years and a 20 ft span. Use 3000 psi normal weight concrete and 60,000 psi steel.

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]
