1a. determine the shear flow distribution(q12, q23, and q34) due to applied sx (sy=0). note that you must simplify the shear flowexpression in terms of sx, h, and s coordinates in each segment. determine the shear flow distribution (q12, q23, and q34) due to applied sx (sy=0). note that you must simplify the shear flow expression in terms of sx, h, and s coordinates in each segment.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

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]
