Consider a film of liquid draining at volume flow rate Q down the outside of a verti- cal rod of radius a, as shown in Fig. P3-16. Some distance down the rod, a fully devel- oped region is reached where fluid shear balances gravity and the film thickness remains constant. Assuming incompressible laminar flow and negligible shear inter- action with the atmosphere, find an expression for v₂(r) and a relation between Q and film radius b.

A cube of lead with a side dimension of 5.0 cm is slowly lowered into the beaker of oil by a thin string attached to a spring scale at a constant rate, as shown in the figure. The density of lead is 11,300 kg/m³. oil density: 960 kg/m3 1 2 3 0.0010 m³ beaker i. What will be the spring scale reading in newtons when the lead has been submerged to location 2? ii. Does the spring scale reading increase, decrease, or stay the same when the cube is lowered from location 2 to location 3? Justify your answer by referencing the pressure of the fluid on the lead cube. iii. The lead cube is lowered from above the oil's surface (location 1) to a spot just below the surface (location 2) until the cube is just above the bottom of the beaker (location 3). Describe any changes in pressure on the bottom of the beaker during this process. Explain your answer.

4–109 Consider fully developed axisymmetric Poiseuille flow-flow in a round pipe of radius R (diameter D = 2R), with a forced pressure gradient dPldx driving the flow as illustrated in Fig. P4–109. (dPldx is constant and negative.) The flow is steady, incompressible, and axisymmetric about the x-axis. The velocity components are given by 1 dP (r² – R²) 4µ dx u, = 0 U, = 0 и where u is the fluid's viscosity. Is this flow rotational or irro- tational? If it is rotational, calculate the vorticity component in the circumferential (0) direction and discuss the sign of the rotation.

An oil film drains steadily down the side of a vertical wall, as shown on figure below. After an initial development at the top of the wall it attains a fully-developed draining vertical oil- film wherein the film becomes independent of "z" and of constant wall thickness. Let the vertical velocity as (w) and using the nomenclatures in the figure such as distance from plate (x), fluid properties, gravity (g) and film thickness ( ). Perform dimensional analysis and determine the function in terms of dimensionless parameters.
