Methane escapes through a small (10-7 m2) hole in a 10 m3 tank. The methane escapes so slowly that the temperature remains constant at 230C. The mass flow rate of methane through the hole is given by  dm/dt = 0.66 pA/sqrt(RT)where p is the pressure in the tank, A is the area of the hole, R is the gas constant, and T is the temperature in the tank. Calculate the time required for the absolute pressure in the tank to decrease from 500 to 400 kPa.
