One-dimensional problems of isothermal gas filtration 
in a porous medium with a quadratic resistance law are considered. 
For the cases of plane and axial symmetry of the problem under constant 
initial conditions, analytical expressions for the gas pressure and 
velocity are obtained and an empirical formula for calculating the 
gas pressure is proposed.
