Calculate the flow rate $($in scf$/$day$)$ of a gas $($molecular weight $16,$ critical pressure $673$ psia, and critical temperature $344R)$ in a porous medium of permeability $400mD,$ thickness $35ft,$ with a pressure of $2000$ psia at the outer boundary $($radius $300ft),$ and temperature of $120F.$ Well diameter is $8$ inches, and well bottomhole flowing pressure is $600a.$ Gas viscosity is constant at $0\mathrm{.}04cp.$ Take Z as a function of pressure.
