Boiler Water Tests A BRIEF DESCRIPTION OF THEIR MEANING AND PURPOSE Expression of Test Results - PPM (parts per million) In water treatment‚ results are most commonly expressed in parts per million (ppm). Other terms commonly encountered are milligrams per liter (mg/l) and grains per gallon (gpg). For practical purposes‚ 1 ppm = 1 mg/l and 1 gpg = 17.1 ppm. The term “ppm” is unitless; that is‚ as long as the same units are used on both sides of the relationship‚ any units can be used. For example

Introduction Brasses are copper zinc alloys. It is a substitutional alloy. Brass has higher malleability than copper or zinc. In general‚ they have good strength and corrosion resistance‚ although their structure and properties are a function of zinc content. The relatively low melting point of brass (900 to 940°C‚ depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc‚ the properties of the brass can

Have you ever crossed a bridge when driving around your city and thought about how it was constructed or how long did it take to be built or is this bridge really safe and will it ever fall down. Well‚ I certainly have and I know that I don’t want for a bridge to fall down whenever I am driving or walking across one. It was 6:05 pm‚ the rush hour in Minneapolis‚ Minnesota and the unimaginable at the I-35W bridge occurred. On August 1‚ 2007 the 1‚907 foot long bridge collapsed leaving dozens of cars

applies a protective graphene coating to copper wire‚ protecting the wire from corrosion that can cause wire failure and enhancing the wire’s electrical conductivity. As a result of its superior conductivity‚ a smaller diameter PCC wire is able to perform the same job as a thicker‚ heavier conventionally-coated copper wire. Competitive coatings (beryllium or cadmium-copper alloys) are heavier‚ vulnerable to corrosion‚ and produce highly-regulated hazardous waste products during production. Substitute

This method prevents further reinforcement corrosion by increasing the PH of the element which results in maintaining the reinforcement passivation. In this paper‚ the re-alkalization sacrificial anodes method is applied to 60 years old carbonated concrete specimens extracted from a demolished building
