It has been proposed to move natural gas from the North Sea gas fields in huge dirigibles, using the gas itself to provide lift. Calculate the force required to tether such an airship to the ground for off-loading when it arrives fully loaded with 1.17 × 106 m3 of gas at a density of 0.796 kg/m3, The density of the air is 1.21 kg/m3, (The weight of the airship is negligible by comparison.)
