As you know some trucks (tankers) always have a chain or wire underneath to discharge electricity. My question is where has the charge come from?

Google on airplane static discharge. It's not the tires that is dominant in accumulating charge in airplanes.pixel01 said:But we don't know what is the dominant. Possibly that the tires can make up 99% of the charge, and we can neglect the air. Say, the airplane, it fly very fast and I do not know if if has problem with charge caused by the moving air.

No. The primary cause is static charge resulting from the dry air rubbing on the skin of the airplane. Did you google on "airplane static discharge"? It would help settle the needless speculation.pixel01 said:Sure that the tires do not dominate the charge in airplanes. They taxi very slowly and just some km on runway.

pixel01 said:I have not googled, but the 2 cases are quite different. Airplanes fly very fast, the friction caused by moving air is big. But the truck moves much slower and the tires always have friction with the surface of the road.

Tankers are charged for several reasons, including the cost of transportation, maintenance and operation costs, and fees for loading and unloading cargo. These charges help cover the expenses associated with the use of tankers.
The charges for tankers are determined by various factors, such as the distance traveled, the type of cargo being transported, the size and capacity of the tanker, and current market conditions. These factors can impact the overall cost of using a tanker.
Tanker charges are typically calculated based on a per-ton or per-barrel basis. This means that the total cost is determined by the weight or quantity of the cargo being transported. Other factors, such as fuel costs and port fees, may also be included in the calculation.
Yes, different types of tankers may have different charges. For example, larger tankers with a higher capacity may have higher charges compared to smaller tankers. Additionally, specialized tankers designed for specific types of cargo may also have different charges.
Tanker charges are typically regulated by government agencies or international organizations to ensure fair pricing and prevent monopolies. However, the specific regulations may vary depending on the country or region in which the tanker is operating.
