A generalized form of differential equation of radial flow for a fluid of small and constant compressibility can be written as: r1r(rkrp)=cttp Derive a solution for the above mentioned differential equation if prevailing flow condition (or period) is steady stat flow, as shown in Figure given below. Radial flow under steady state conditions The relevant boundary conditions are: p=pe=constant,atr=rep=pwatr=rwtp=0forallrandt We also know that Darcy's Law for radial for between can be written as q=2khlnre/ww(PePt) Show your work (i.e. derivation steps you used for obtaining the final form of your solution)?
