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.
The solid phase (calcium hypochlorite) is less corrosive than liquid bleach (sodium hypochlorite) and will cause less damage to the produce and equipment. The disadvantage of the solid is that it is less stable at normal storage conditions. All types of chlorine will form hypochlorous acid (HClO) when added to water.
