ASSIGNMENT $1$

State the dimension for convective mass transfer coefficient. How does it differ from convective heat transfer coefficient.

Explain the significance of Schmidt, Sherwood and Lewis numbers in mass transfer analysis.

Describe giving examples "equimolal counter diffusion" and "one component diffusing into a stationary component".

Give an example for simultaneous heat and mass transfer.

In a major human artery with an internal diameter of $5mm,$ the flow of blood, averaged over the cardiac cycle, is $5c{m}^3*s^{-1}.$ The artery bifurcates $($splits$)$ into two identical blood vessels that are each $3mm$ in diameter. What are the average velocity and the mass flow rate upstream and downstream of the bifurcation? The density of blood is $1\mathrm{.}06g*c{m}^{-3}.$
