One of the most popular books in the oil and gas field "GPSA Engineering Databook", 11th edition, SI units provides a chart (Fig 17-4) in Section 17, "Fluid Flow & Piping" for the equivalent lengths of the commonly used fittings and valves as a function of the resistance coefficient and the nominal pipe diameter. Concentric & Eccentric Reducers – Standard Weight (Continued) Nominal Pipe Size Length (H) Approximate Weight (in Pounds) 16 X 6 14 67.4 Equivalent Length: Equivalent length of a pipe fitting is defined as the frictional losses caused due to the pipe fitting that is equivalent to frictional losses caused by a straight pipe of length (L/D) e, where . L. e. is the equivalent length and is the diameter of the pipe. Table 3.4 of your textbook . D shows (L/D) e. for different types ... How to Determine Equivalent Length Calculate the equivalent length of the liquid line for the following condensing unit with DX air-handling unit. The liquid line is composed of the following elements: • 30 ft (9.14 m) of 1-3/8 inch (35 mm) piping • 4 long radius elbows • 1 filter drier • 1 sight glass • 1 globe type isolating valve

Table A. Pipe Sizing Data Maximum deliver capacity of pipes of different diameters and lengths in cubic feet of gas per hour for an initial pressure of 2.0 PSI and a gas of .06 specific gravity.

To account for pressure loss through the fittings, next add 50 percent of the actual length of piping as an all-inclusive fitting allowance (210 feet x 1.50 = 315 feet). The final result is that all pipe sizes will be chosen from the 350-foot (106,680 mm) row of the table. Determined sizes are shown in Table 3.

WATER PIPING AND PUMPS Distribution Systems 1 Introduction In this TDP module we will cover major topics associated with chilled water piping, and to a limited extent, hot water piping. We will discuss the three types of piping systems and the four basic piping distribution designs used to supply and return water to HVAC hydronic equipment.

Friction Loss in Fittings Valves As an aid, liquid sizing constants (Cv values) are shown for valves. These values are defined as the flow rate through the valve required to produce a pressure drop of 1 psi. To determine the pres-sure drop for a given GPM the following formula may be used. ∆P = (G2)(SG)/Cv2 where: AP = pressure drop G= Flow ... Looking for steel pipe size charts? The ASME B36.10 and ASME B36.19 specifications cover the dimensions of seamless and welded steel pipes for high and low-temperature service, providing combinations of pipe outside and inside diameter (OD, ID), pipe thickness (WT, designated in “schedule”) and pipes theoretical weights (in pounds per foot and kilogram per meter). 10-10 Schematic diagram of a typical cross section of a ductile-iron pipe, 183 10-11a Annealed ductile-iron pipe before over-blasting, 184 10-11b Same ductile-iron pipe resulting in blisters and disbondment from over-blasting, 184 10-12 Typical risk model, 188 11-1 Unloading pipe with a forklift, 196 11-2 Unloading pipe with a crane, 197

Engineering & Design Data FLOW VELOCITY & FRICTION LOSS Friction Loss Through Fittings Friction loss through fittings is expressed in equivalent feet of the same pipe size and schedule for the system flow rate. Schedule 40 head loss per 100' values are usually used for other wall thicknesses and standard iron pipe size O.D.’s. DUCT DESIGN, LEVEL 1: FUNDAMENTALS Distribution Systems 2 Space Availability The sizing criteria will often be defined by the space available to run the ductwork (Figure 1). Ceiling plenums, duct chases, and obstructions such as walls and beams often dictate that a cer-tain size duct be used, regardless of whether or not it is the best size from a Dimension l is the effective length of a fitting, which is added to the overall length of the ductwork system.

lent length of pipe) should be considered for any piping run with four or more fittings [see Table A.2.2]. A.2.3 Undiluted liquefiedpetroleum tables. Capacitiesin thousands of Btu per hour of undiluted liquefied petroleum gases based on a pressure drop of 0.5-inch w.c. (125 Pa) for different sizes and lengths are shown in the International Fuel Gas Code. Oct 25, 2015 · Table 8-12 lists equivalent lengths of the more common fittings and valves and is an example of the data provided by the ASHRAE for sizing pipes. The pressure drop in pounds per square inch per 100 feet is determined by dividing 50 percent of the initial pressure by the equivalent length of the longest piping circuit. To account for pressure loss through the fittings, next add 50 percent of the actual length of piping as an all-inclusive fitting allowance (210 feet x 1.50 = 315 feet). The final result is that all pipe sizes will be chosen from the 350-foot (106,680 mm) row of the table. Determined sizes are shown in Table 3. Note that each pipe section has its own fitting selector. If a particular fitting is not shown, you may enter it manually in one of the bottom lines. You will have to look up the "equivalent pipe length" and enter it in Column Q. The value should be the total equivalent length for the number of fittings you entered. Fitting equivalent length ...
