http://www.w3.org/ns/prov#value | - For instance, a 20 gallon (90 litre) petrol tank has to be able to bear the 142.56 Lbs* weight of its contents and still retain its shape. (Incidentally, Diesel is heavier still.) The most interesting point is that the tank is only designed to do this when it is mounted up to (or into) the vehicle by bolts and / or straps using the designed mounting points and other fixings. * 90 litres x 0.72 Kgs
