Salinity is approximately equal to the weight, in grams, of salt dissolved in 1000 g of seawater. This would be the salt concentration in parts per thousand (). Average ocean water has a salinity of 35.0. This means that 1000 g of average seawater contains 965 g of water and 35 g of salts.
From Wikipedia, the free encyclopedia. RTV Silicone (room temperature vulcanization silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium-usually from 15 Shore A to 40 Shore.n order for the RTV silicone to reproduce the surface texture, attention is paid to the cleanliness of the original. Vacuum deairing removes entrained air bubbles from the mixed silicone and catalyst to ensure optimal tensile strength, which affects reproduction times.
  RTRP stands for Reinforced Thermosetting Resin Pipe and FRP stands for Fiberglass Reinfoced Plastic Pipe. FRP is a composite material consisting of a thermosetting polym â¦ er, often a type of polyester, reinforced with glass or other fibers.Glass fibers provide strength and stiffness to a composite material.  In fact,the RTR pipe have a m â¦ ore approperiate name as GRE(Glass  Reinforced Epoxy) Pipe, since that uses Epoxy Resin instead of  Polyester.    GRE Pipe have much superior properties than common RTR Pipe,  especially in properties of high pressure resistant.
