1. Aerofoil
- The flight of an aeroplane is based on the principle about the effect of the flow of air around its wings, which is, the aerofoil.
- An aerofoil shape has a rounded front edge and pointed (sharp) trailing edge. The top surface is arched (curved) and the bottom is flat.
-When a wing in the form of aerofoil moves through air, the flow of the air over the top has to travel faster to cover the longer distance (compares the lower portion) and creates a region of low pressure. The flow of air below the wing is slower resulting in a region of higher pressure.
-The difference between the pressures at the top and the bottm creates a NET UPWARD FORCE..(remember! bottom part higher pressure..upper part lower pressure).This is called a Lift and helps the plane to take off.
-In addition to that, inverted aerofoils are used in racing cars to create a donward force and stabilize the cars at high speed.
2. Bunsen Burner
- When a bunsen burner is connected to a gas supply, the gas flows at high velocity through a narrow passage in the burner, creating a region of low pressure.
- The outside air, which is at atmospheric pressure, is drawn in an mixes with the gas.
-The mixture of gas and air enables the gas to burn completely to produce a clean, hot fire.

Which spray has recently been banned in the US?
Given the related/alternate questions I could only imagine we're referring to pesticides. Such a list has been added to the "related links" area. The Environmental Protection Agency allowed the residue tolerances for an insecticide named carbofuran (trade name Furadan) to expire at the end of 2009. This in essence bans the pesticide from all US uses, since the manufacturer will not continue to produce it.
