For fully developed laminar flow through a parallel-plate channel, with a constant (and negative) pressure gradient of dP/dx, the x-direction momentum equation has the form: μ(d^2u/dy^2) = dp/dx = constant

Required:
a. Starting with this expression derive an expression for the laminar, fully developed flow profile uy) between a parallel plate channel where there is a distance A between the two plates.
b. What is the mean velocity in the channel?

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]
