Transport of goods by rail is carried out by different types of railway carriages

On some railways meet special freight railway carriages in the form of a huge cylinder, intended for the transport of gas. One such railway carriage is usually weighs about 10 tons, its capacity - 50 cubic meters. Suppose it laden with hydrogen, cubic meter of which weighs 100 g. How many will weigh railway carriage with a load?

The railway carriage is filled with such a burden, not only will not weigh more than empty, but on the contrary, it will be easier.

To fill it with hydrogen, it is necessary to first remove the air, 50 cubic meters of which weigh around 65 kg, and 50 cubic meters hydrogen weigh approximately 5 kg. Consequently, the railway carriage will be lighter by 65 - 5 = 60 kg.

Also gas tank railway carriages are intended for transport of fluids: oil and products of its processing, chemically active and corrosive liquids. Tank railway carriage may be intended for the carriage of goods without excessive pressure or under pressure. Tank railway carriage is a horizontal container of cylindrical shape, closed at the sides elliptic bottoms. The capacity of the tank or its separate sections have a device for loading and unloading. Vessels may have special tanks or thermal insulation coating equipment to heat the transported product, as well as instruments for its control.
