As you are probably aware of the US $29bn acquisition deal made by Block (previously known as Square), an American fintech company, to take over After pay, a successful Australian fintech, in 2021 - early 2022. Suppose that, to finance this buyout, Block/Square needed to raise funds via international bond sales. More specifically, it considered to issue Kangaroo bonds, and USD-denominated Eurobonds in different regions including Asia, Latin America, Europe.

Taking into account the recent macroeconomic environment, compare and contrast the benefits of each financing option. Which one do you think would be more beneficial for Block/Square?

5.2G BSL Start the problem by setting up a momentum balance over a thin shell of thickness Ar. 2G, Laminar Flow of Falling Film on Outside of a Circular Tube In a gas absorption experiment a viscous fluid flows upward through a small circular tube and then downward on the outside. (See Fig. 2.G.) Set up a momentum balance over a shell of thickness Ar in the film, as shown in the figure. Note that the "Momentum in" and "Momentum out" arrows are always taken in the positive r-direction in setting up the balance, even though in this case the momentum turns out to be flowing in the negative r-direction. a. Show that the velocity distribution in the falling film (neglecting end effects) is - [1 - ()*+ 20 10 (2)] In b. Obtain an expression for the volume rate of flow in the film. c. Show that the result in (b) simplifies to Eq. 2.2-19 if the film thickness is very small.
