The upstream pressure on a rock sample is 0.113MPa and the downstream pressure is 0.1MPa. Under this pressure difference, a gas with the viscosity of 0.018 mPa·s flows through the rock sample. The diameter of this sample is 2.5cm, its length is 2.8cm. The volumetric flow rate at the outlet face is 0.514cm3/s. Calculate the gas permeability of this rock sample.
