Older Petrol-trucks were supplied with a chain or strap to discharge static electricity; this was because natural rubber-tires manufactured prior to the mid 1940's would generate a powerful static charge on the chassis of the vehicle which caused numerous fires during fuel transfer operations.
Modern "Synthetic Rubber-Tire" actually have enough Carbon in the rubber compounds so they conduct enough electricity and any static electrical charge is dissipated back to the road surface directly through the tires. Now therefore there is no longer any need for a dissipation-strap or a Grounding-Chain".
A tanker is used to transport the Petrol from storage tanks to the petrol station.
A typical petrol tanker can carry between 30,000 to 40,000 liters of petrol, although some larger tankers can hold up to 60,000 liters or more. The exact capacity depends on the design and size of the tanker, as well as regulations regarding transportation. These tankers are specifically built to safely transport liquid fuels over long distances.
Electric charge can build up in a petrol tanker due to friction between the flowing liquid and the tanker walls, creating a separation of charges. This can be exacerbated by the movement of the liquid, leading to a transfer of electrons and the accumulation of charge on the tanker surface. Factors like temperature, humidity, and the type of materials involved can also impact the buildup of electric charge.
Most likely, this is to discharge any static electricity that the tanker may have accrued during its journey. Such static can be dangerous because it may cause the petrol to ignite; therefore, the wire 'grounds' the tanker (i.e. it allows the electricity to pass harmlessly into the ground) and removes this threat.
It is a ship known generally as a tanker.
Because even if there's a slight static charge in the tanker, it could ignite the petrol and explode. If it's connected to the ground by a wire, then all the static charge in the truck is removed (ie grounding the truck).
I am not sure, I wrote tanker.
it depends on the tanker but usually about 9300 gallons
A metallic chain on a petrol supply tanker is designed to roll on the road to ensure proper grounding and prevent the buildup of static electricity. As the tanker moves, friction can generate static charges, which pose a fire hazard when transporting flammable liquids like petrol. By rolling on the road, the chain helps dissipate these charges safely into the ground, reducing the risk of ignition during loading or unloading operations.
The oil company who provided the gas/petrol. However, the police would probably guard the tanker until another driver arrived.
Sure, just change the tank and all the plumbing. If you were trying to re-purpose the tank, no, the tank has to survive a 300 psi pressure test
Road tankers are large lorries that carry large tanks that can hold bulk liquids or powder. A milk tanker will carry milk. And an oil tanker will carry petroleum products - petrol, diesel, oil, etc.
