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.
â¦ and will cause the metal to corrode Most metals with Oxidise in air, however not all will rust. Aluminium for example is too reactive to corrode, a thin layer of Aluminium oxide forms at the surface that provents the metal below from rusting. Gold on the other hand is inert and with not oxidise readily in air.
