A previous article published by Katmar Software discussed the available methods including the Equivalent Length Method for calculating the pressure drops in pipe fittings and valves. The present article gives Equivalent Length values for a wide variety of pipe fittings and valves that can be used as described in that article.

Steam Distribution

Allowances are for streamlined soldered fittings and recessed threaded fittings. For threaded fittings , double the allowances shown in the table. The equivalent lengths presented above are based on a C factor of in the Hazen-Williams friction loss formula. The lengths shown are rounded to the nearest half-foot. Open navigation menu.

If you are looking for a calculator to perform pipe sizing and pressure drop calculations please jump to the AioFlo page. The sizing of pipes for optimum economy requires that engineers be able to accurately calculate the flow rates and pressure drops in those pipes. The purpose of this document is to discuss the various methods available to support these calculations. The focus will be on the methods for calculating the minor losses in pipe sizing and to consider in particular the following aspects:. Over the years excellent progress has been made in developing methods for determining the pressure drop when fluids flow through straight pipes. Accurate pipe sizing procedures are essential to achieve an economic optimum by balancing capital and running costs. Industry has converged on the Darcy-Weisbach method, which is remarkably simple considering the scope of applications that it covers.

When using the Hazen-Williams method, the most accurate way to account for resistance due to valves and fittings is to add an equivalent length for the valve or fitting to the pipe length. These equations were developed using the Darcy-Weisbach method, which is why they are not as accurate when used with the Hazen-Williams method. The executable file, located at the bottom of the page, contains the following tables:.

By: Jorge Solorio on August 28th, In our previous post , we discuss the various formulas used to determine flow rate, flow velocity and pressure loss, as well as the factors that piping material selection plays in optimizing fluid handling. Read the full post, here. When designing industrial piping systems, engineers want a system that will minimize expenses over the long term. Excessive energy consumption increases costs and hurts the bottom line. Piping system design attempts to maximize energy usage by minimizing resistance to the fluid flow. The harder pumps have to work to move the fluid through the system, the more energy consumed and money spent.

 Хуже. Если Танкадо убьют, этот человек опубликует пароль.

Ты же меня прихлопнешь. - Я никого не собираюсь убивать. - Что ты говоришь. Расскажи это Чатрукьяну.

 - Какой смысл хлестать мертвую кобылу. Парень был уже мертв, когда прибыла скорая. Они пощупали пульс и увезли его, оставив меня один на один с этим идиотом-полицейским. Странно, - подумал Беккер, - интересно, откуда же взялся шрам.

 - Он замолчал, словно подбирая нужные слова.  - Этот шифр взломать невозможно. Сьюзан посмотрела на него и едва не рассмеялась.

 Вы правы, сэр. Но он не искал глазами убийцу. Жертва всегда ищет глазами убийцу. Она делает это инстинктивно. Фонтейна эти слова озадачили.

 Хватит врать! - крикнул Стратмор.  - Где. Хейл сдавил горло Сьюзан. - Выпустите меня, или она умрет.

 - Вспомни арифметику, Сьюзан.
