A uniform oil flow enters a pipeline at a flow rate of 0.05 m3/s. The diameter of the pipeline is 15 cm. It is well known that a boundary layer will develop during the initial portion of the duct and will eventually reach to a fully developed flow. Use the concepts learned in the flat plate boundary layer theory to predict the developing region length (entrance length) or the length after which fully developed flow prevails. The consideration of flat plate boundary layer theory for the present problem will results in some error in predictions. List the reasons for this error. Take density= 890 Kg/m3and dynamic viscosity as 0.288 Pa.s
3. Pressure Flow, Flat Plates. Adverse pressure gradients in flow over bodies lead to flow reversal & separation, wakes, and increased drag. To examine such behavior, consider fully developed, laminar flow between two flat pates a distance 8 apart. The bottom plate is fixed, and the top plate moves with speed U (representing the outer flow over a boundary layer of thickness 8). (a) Derive the critical adverse pressure gradient, (dp/dx)*, above which there will be flow reversal, by solving the N-S equation in the coordinates shown, to get a relation for u(y), du/dy, and the critical (dp/dx)* in terms of 8, U, and u above which there μ will be flow reversal at the lower plate. (b) If 8 = 5 mm and U = 10 m/s, evaluate (dp/dx)* if the fluid is air.

a) A sphere (Case 1) is modified with a fairing at the back of sphere (Case 2) and a housing (Case 3) to make it more streamline as shown in Figure 1. By assuming the turbulent flow condition for all cases: Draw the flow profile for each case, Discuss the effect of modification using fairing and housing on the (1) friction drag, (2) pressure drag, and (3) total drag.
