Friction Loss In Ductile Iron Fittings

The Hazen–Williams equation is an empirical relationship which relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems such as fire sprinkler systems, water supply networks, and irrigation systems. It is named after Allen Hazen and Gardner Stewart Williams.

BLUe BRUte™ 5 sURge design it is important to note that for the same conditions of interrupted flow, the surge pressures generated in pipe with high tensile moduli will be greater than the surges in low moduli (pvC) pipe of similar dimensions.

Interference fits may increase or decrease at elevated temperatures depending upon the thermal expansion rates of the various parts. For example, an idler pin of low or medium expansion rate installed in a head with a high expansion rate will lose its interference or.

PFTE is an abbreviation for PolyTetraFluoroEthylene; it’s a fluorocarbon-based polymer. TEFLON is a registered trademarked brand of PTFE. PTFE’s mechanical properties are low compared to other plastics, but it can be used over a wide range of temperature range of -100F to over 400F.

The Viking 4” Model M-2 Check Valve is a general purpose rubber-faced check valve approved for use in fire service systems. The Model M-2 Check Valve is manufactured with a ductile iron body, a stainless steel clapper assembly, brass seat, and an EPDM rubber.

Ductile Iron Flanged Pipe for Water and Other Liquids. Flanged pipe and fittings are typical components in rigid piping systems. Such systems are ANSI /AWWA Standards particularly suited for above ground installation in the following: water filtration plants, sewage disposal plants, wastewater treatment plants, pumping stations and industrial plants, per AWWA C115/21.15.

This is a list of ASTM International standards. Standard designations usually consist of a letter prefix and a sequentially assigned number. This may optionally be followed by a dash and the last two digits of the year in which the standard was adopted.

The physical properties of Transition Metals like density, melting points, boiling points, strength are described and discussed along with a description of the important transition metal chemical properties of e.g. titanium, vanadium, manganese, iron, cobalt, nickel, copper and zinc. There are also sections on how metals can be improved to increase their usefulness e.g. alloys and they are.

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.

Velocity Analyzer The Velocity Analyzer Utility calculates the Reynolds Number, a key measure of fluid turbulence and non-laminar flow.The Reynolds Number is a function of pipe diameter(in), flow(gpm) and kinematic viscosity(Sq-Ft/sec).The Velocity Analyzer uses the Reynolds Number and measures of pipe roughness to calculate Moody’s f and pipe friction loss(psi/ft) using the Darcy-Weisbach.
