The measure of a major arc is C10-448A-888484be x Â° $%# greater than 180, and equal to 360 minus the measure of the minor arc with the same endpoints. m âADB = 360 - mAB â = 360 - x A semicircle is an arc with endpoints that lie on a diameter.
Process Chemicals Corrosion. Chlorine. The flow rate of liquid chlorine through carbon steel pipework is restricted to 2 m/s to avoid removing the ferric chloride coating on the pipe surface which protects against erosion / corrosion of the carbon steel. Wet chlorine gas corrodes mild steel.
Chlorine is used in industry and in household cleaning products. Chlorine was also the first poison gas to be used as a weapon during World War I. Some of the chemical/physical properties of chlorine include: 1  Chlorine is a yellow-green gas at room temperature.2  Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations.hlorine was also the first poison gas to be used as a weapon during World War I.
