1. (4 points) The inlet of a two-dimensional duct, shown below, is of width b and contains frictionless fluid of constant density p. The velocity in one half of the duct is Ui and the other half is 0.5U1. The two streams do not mix. The outlet of the duct is of width 0.5b. The flow is parallel at the duct entrance and exit, so that the pressure is uniform across the two sections. By...

Liquid saline flows steadily along the duct in Figure 1, which is part of an infusion set. The duct has constant cross-sectional area Ao-18 mm. The fluid velocity at the inlet section is Vo 0.35 m/s. A drug is added to the saline through a side port connected to the main duct at an angle θ 45°. The cross-sectional area of the side access is A1-10 mm2 and the drug is injected with velocity V,-0.8 m/s. The drug has the...

Water at 20 C is steadily flowing through a diverging pipe section that is inclined by an angle of 30° with respect to the horizontal (See the figure) The total testing section length is 20 m long with an initial pipe diameter of 10 mm (Section 1) and final diameter of 20 mm (Section 2). The small diameter section shows a gage pressure of 100 kPa and average flow velocity 10 m/s. Other values will be obtained by reaching complete...

Water can be considered as a non-viscous incompressible fluid of density p. A laboratory set-up is such that water flows through a pipe, exhibiting a laminar and steady-state flow. At the top end of the pipe, the flow tube has a cross-sectional area A and point 1 (located on the central streamline) is exposed to the ambient environment. The pipe drops through a A vertical distance h7 while its area decreases to when it reaches point 2 (also on the...
