Consider the diffusion of a drug from a cylindrical disk. for a thin disk (thickness h< < r, where r is the radius), diffusion from the disk into the surrounding tissues can be treated as a one-dimensional problem in the direction along the axis of the disk. (a) a drug is being released uniformly from the material contained in the disk at a fixed rate (moles per unit volume per unit time). find an expression for the steady-state concentration profile of the drug inside the disk. you may assume that the drug diffuses so freely in the surrounding tissue, relative to within the disk, that the surface concentrations c(x=0) and c(x=h), can both be assumed to be zero (b) compute the steady flux (moles per unit time) of drug out of the disk at x-o and x =h.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
