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.
Well acids and bases are both corrosive and bases are more corrosive to the skin as compared to acids. Niw an acid is made corrosive by tge fact that an acid has H+ present, which is looking for electrons now the only thing that an acid does on a metal surface is to take the metals electrons and that is What we term as corrosion.
