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.
Rash from Chlorine. Chlorine is typically known as a skin irritant. A chlorine rash can occur following an exposure to the chemical. It is often associated with exposure to chlorinated water like in swimming pools or hot tubs. Preventing the rash includes avoiding or minimizing exposure to chlorine.
