**4-51**Converging duct flow is modeled by the steady, two-dimensional velocity field of Prob. 4-16. A fluid particle (A) is located on the x-axis at \( x = x_A \) at time \( t = 0 \) (Fig. P4-51). At some later time \( t \), the fluid particle has moved downstream with the flow to some new location \( x = x_{A'} \), as shown in the figure. Since the flow is symmetric about the x-axis, the fluid particle remains on the x-axis at all times. Generate an analytical expression for the x-location of the fluid particle at some arbitrary time \( t \) in terms of its initial location \( x_A \), and constants \( U \) and \( b \). In other words, develop an expression for \( x_{A'} \). (Hint: We know that \( u = \frac{dx_{particle}}{dt} \) following a fluid particle. Plug in \( u \), separate variables, and integrate.)**Diagram Explanation:**The diagram labeled "FIGURE P4-5I" shows a schematic of a converging duct flow with the velocity field depicted by arrows pointing rightward, representing fluid motion. Initially, a fluid particle is placed at point \( A \) on the x-axis. As time progresses, the particle moves to point \( A' \) further right, staying on the x-axis due to symmetry in the flow. **4-63**A general equation for a steady, two-dimensional velocity field that is linear in both spatial direction (\( x \) and \( y \)) is:\[\vec{V} = (u, v) = (U + a_1x + b_1y)\hat{i} + (V + a_2x + b_2y)\hat{j}\]Where \( U \) and \( V \) and the coefficients are constant. Their dimensions are assumed to be appropriately defined. Calculate the shear strain rate in the \( xy \)-plane.

q21 The density of steel usually ranges between 7750 and 8050 kg/m3. This is much more than the density of water 1000 kg/m3. Briefly explain why steel ships can float on water. Hint: In your answer, make sure that the explanation is related to a physics principle covered in this unit.

VISCOUS FLOW : Poiseuille’s law, Stokes law or Reynolds Number One way to administer an inoculation is with a “gun” that shoots the vaccine through a narrow opening. No needle is necessary, for the vaccine emerges with sufficient speed to pass directly into the tissue beneath the skin. The speed is high, because the vaccine ( = 1100 kg/m3) is held in a reservoir where a high pressure pushes it out. The pressure on the surface of the vaccine in one gun is 4.1 x 106 Pa above the atmospheric pressure outside the narrow opening. The dosage is small enough that the vaccine’s surface in the reservoir is nearly stationary during an inoculation. The vertical height between the vaccine’s surface in the reservoir and the opening can be ignored. Find the speed at which the vaccine emerges.
