The daily production from a certain oil well is $718\mathrm{.}5bbls.$ The drainage area is $160$

acre where the average pressure is at $1850.$ If the oil viscosity $=2\mathrm{.}2cP,$ well$-$bore

radius $=0\mathrm{.}5ft,$ thickness of pay zone $=16ft,$ and formation permeability $=180mD,$

what is the well flowing pressure? Note $1$ acre $=43560f{t}^2.$
