Equivalent Length Method The equivalent length method (The L e /D method) allows the user to describe the pressure loss through an elbow or a fitting as a length of straight pipe. This method is based on the observation that the major losses are also (v 2 /2g).

An elbow is a pipe fitting which is used as a connection point between two lengths of pipes to produce a change in the direction of flow in the pipe, usually at an angle of 90 , 45 or 180 . Elbows are also commonly referred as bends, and are available in a range of materials such as stainless HDPE, carbon HDPE, alloy HDPE, nickel alloys, duplex, and cupro nickel.

HDPE pipe elbow is an important parts in pluing pipeline systems and used to change the fluid directions. It ranges in different types as per body material there are stainless HDPE elbow, carbon HDPE elbow, and alloy HDPE; As per fluid directions there are 45 degree , 90 degree elbow and 180 degree; As per elbow length and radius there are short radius elbow (SR elbow) and long radius Puhui Pipe manufacturer in China
length or rather total equivalent length of that pipe route including all valves, fittings, etc. So, apart from the total length of all horizontal and vertical straight pipe runs, we need an associated length of straight pipes of the same diameter, which will incur the same Puhui Pipe manufacturer in China

A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in pluing to manipulate the conveyance of water, gas, or liquid waste in domestic or commercial environments, within a system of pipes or tubes.
Review. Inside the wall of a house, an L-shaped section of hot-water pipe consists of three parts: a straight, horizontal piece h = 28.0 cm long; an elbow; and a straight, vertical piece ℓ = 134 cm long (Fig. P18.6). A stud and a second-story floorboard hold the ends of Puhui Pipe manufacturer in China
Types: 45 degree HDPE elbow, 90 degree HDPE pipe elbow, 180 degree elbow Size Range: 1/2”, 1”, 2”, 3”, 4”, 6”, 8”, 10”, 12”, 16”, 20” to 48”. Thickness: SCH 10, SCH 40, SCH 80
Using the table of fittings and equivalent lengths above we find that the equivalent length for the 90 elbow is 12 pipe diameters. Taking the pipe length and nuer of elbows we calculated the equivalent length of the pipe work for pressure loss purposes.
For example, a 20 mm elbow offers the same resistance to ﬂow as a 20 mm pipe 0.8 m long. Figure 5.5 shows the equivalent pipe lengths for the ﬁttings in the example in ﬁgure 5.4. (g) Effective pipe length. The effective pipe length is the sum of the measured

The definition of the Equivalent Length of a pipe fitting is the length of pipe of the same size as the fitting that would give rise to the same pressure drop as the fitting. It has been found experimentally that for a given type of fitting (e.g. a long radius elbow) the Equivalent Length (L e ) is larger for larger fittings.

3/3/2015· For example an 8” 90 deg. elbow SDR 17.6 shows an equivalent length of 14.0 ft. This means that for every 8” 90 deg. elbow you have in your system you need to add 14.0 ft. equivalent length of pipe to the total length of pipe in your system when calculating the total friction loss.
Note that the value (that is, 28.28 inches) for the length of pipe H obtained by the aforementioned equation is the calculated length and does not allow for the projections of the elbows. In other words, pipe H (as calculated by this equation) is too long and must be shortened so that the elbows will fit.
