  • Re: Derating Factors for Cable

    Sir, The cable size has to be large enough so the heat losses into the surrounding soil do not heat the cable beyond the temperature the insulation is rated for. Knowing the configuration of adjacent ducts in the cable bank and the temperature rating of the insulation are both essential. Keep searc...

  • Re: cable ampacity

    Hi Not to confuse at all, but there is more to just looking up on a table for the current carrying capacity of a cable. in any chart you look up there will be some standard specifications linked to the value. IE, depth of cable, or on a rack or in the air or in a duct, How many cables run together,...

  • Re: cable sizing calculation

    To size the current you should refer the relevant bs,is or IEC standards. Alternatively from cable manufacturer tables(ducab or polycab or oman) one can calculate the current but several factors have to be taken into consideration 1. cables being laid in air,duct or buried ground.

  • Re: Static Pressure

    You can also find static pressure drop of a duct given the duct size, volume of air flow (cfm) and velocity. You can also use a chart or an engineering design tool called a ductculator. For a given size of duct, lets say for example 24"x12" in a HVAC application. Industry standard of supply air flow...

  • Re: Flase Floor.Measurement of air leakage.Testing Procedures.

    It is used in places, where a large amount -mostly electronic - equipment is packed together in rows of racks or cabinet, like internet hubs, server farms, large computing centers, supercomputers. You get the idea. Such equipment generally is positively aircooled: individual fans or blowers force...

  • Air Flow Validation in Large Size Ducts

    We are having secondary ducts of size 4000X 5000 mm size with aerofoil and primary air duct of 2000X3000 mm size with ventury for air flow measurement. Pl help me in validation of these flow measurements using pitot tube or any other means.

  • Reinforcement Analysis on Duct Transition

    We employ an equipment for which circular ducts are to be used. This particular application requires the duct transition to reinforced with rectangular bars at equal intervals but I am unsure of a method of doing any analysis for the strength -given the design conditions,materials and sizes. Any h

  • ASP.NET: Create Snazzy Web Charts and Graphics On the Fly with the .NET Framework

    Knowledge workers can understand data more effectively when raw numbers are presented in a graphical format. This is especially true when displaying database information on a Web page, where a simple chart can make the difference between a dry presentation and a vivid data source. In the past, creating dynamic, data-based charts on the fly in ASP required purchasing a third-party, image-generating COM component. Now with ASP.NET, developers can access the .NET Framework''s drawing classes directly with C# to create dynamic images and charts.Scott MitchellMSDN Magazine February 2002

FREE Motor & Drive Sizing Software

the guesswork out of motor sizing. Complex calculations, that take hours by hand, are now handled quickly by the software," says developer Rick Armstrong. It takes a systems approach to sizing by considering the amplifier and power supply ratings in addition to those of the motor. Application mechanisms that can be selected include: leadscrew, rack and pinion, conveyor, nip rolls, spindles and direct drive rotary and linear devices. Motion profiles include simple triangle, trapezoidal and custom...
