orphan date November 2007 In astrodynamics , A canonical unit is a unit of measurement defined in terms of an object s reference orbit . In this system, a reference mass, for example the sun, is assumed to be 1 mass unit and the mean distance from the orbiting object to the reference object is considered the distance unit . Canonical units are useful when the precise distances and masses of objects in space are not available. However, by setting the mass of a given object to be 1 mass unit and the mean distance of the reference object to another object in question, many calculations can be simplified. Overview The distance unit math DU math is defined to be the mean radius of the reference orbit. The time unit math TU math is defined by the gravitational parameter math mu math math mu G M , math math G math is the gravitational constant math M math is the mass of the central reference body For Canonical Units, the gravitational parameter is defined as math mu 1 frac DU 3 TU 2 math The quantity of the time unit TU can be solved in another unit system eg. the metric system if the mass and radius of the central body has been determined. Using the above equation and applying dimensional analysis , set the two equations expressing math mu math equal to each other math mu G M 1 frac DU 3 TU 2 math The Time unit TU can be converted to another unit system for a more useful qualitative solution using the following equation math TU sqrt frac DU 3 G M math Approximate unit conversions are as follows 1 DU 6378.1 Km 20,925,524.97 ft 1 DU TU 7.90538 Km sec 25,936.29 ft sec 1 TU 806.80415 sec Astronomical Units An Astronomical units is canonical unit based on the orbit of the Earth around the Sun See also Astronomical unit Conversion of units References Roger R.

Multiple issues wikify March 2012 unreferenced February 2007 orphan November 2009 A protective finishing coat is a substance or chemical composition applied to the surface of an object that provides a barrier of protection from external elements. Polishes use a highly refined abrasive generally finer than 4,000 grit that is suspended in a liquid carrier. The polish wears away the surface to create a smooth surface. The smoother the surface the higher the resulting gloss or perceived shine . A protective finishing coat is applied after polishing to preserve the surface and help resist further oxidation or weathering. Effective finishing coatings penetrate the surface pores and use these pores to which the protective film anchors to.

Image SSPC.v2.png right Society for Protective Coatings SSPC The Society for Protective Coatings SSPC is a professional organization for the industrial coating s industry. It was founded in 1950 as the Steel Structures Painting Council , a non profit association concerned with the use of coatings to protect industrial steel structures such as bridges, ships, water tanks, and locks and dams. Since the original mission of the organization evolved over the years to include structures built with materials other than steel concrete, composite materials, etc. , the name was changed in 1997 to The Society for Protective Coatings. As of 2007, there are approximately 8,300 members worldwide. There are also approximately 780 corporate members. Industrial painting contractors are a primary beneficiary of SSPC s efforts. SSPC develops and publishes widely used industry standards for surface preparation, coating selection, coating application, painting contractor certification, and testing. Standing committees periodically review and update the standards as required. In addition, SSPC publishes the Journal of Protective Coatings & Linings as well as books, training courses, and information regarding environmental regulations and health and safety issues that affect the protective coatings industry. An annual conference, the Paint and Coatings Expo or PACE , is held in the United States each year for SSPC members and affiliates. Other regional meetings are held throughout the USA and other parts of the world via SSPC s Chapter system.
