Pipe Flow Software ® Official - Pipe Flow & Pressure …

However, the Pipe Flow Wizard software does not allow the use of equivalent length of pipe. It actually calculates the fittings pressure loss using well known and established fitting loss equations. The ''K'' factor of a fitting may be calculated from the ''Equivalent length'' (in m or ft.) if the friction factor and the Internal diameter (in m or ft.) are known.

2012 SEATTLE FUEL GAS CODE 143 APPENDIX A (IFGS) SIZING AND CAPACITIES OF GAS PIPING (This appendix is informative and is not part of the code.) A.1 General piping considerations. The first goal of deter-mining the pipe sizing for a fuel gas piping system is to make

Effective length of Elbows - Pipelines, Piping and Fluid …

9/9/2004· For a 90 degree elbow, the equivalent length is 30D or 30 times the diameter of the pipe in feet. Hence for a 16 inch long radius elbow, the equivalent length of this elbow is 30 x 16/12 = 40 feet. Of course, if there are 8 elbows in the system, the total equivalent length will be 320 feet.

Equivalent Length Calculator - EnggCyclopedia

The equivalent length calculated here can be added to the straight pipe length to obtain the total equivalent length of the whole piping system. For minor variations in flow this equivalent total length remains the same and changes in pressure drop may be obtained by directly multiplying the pressure drop per unit length by this total equivalent length.

Equivalent Length - Explanation

Explanation to Equivalent Length In order to simplify the calculation of equivalent length of pipe fittings and valves in pluing engineering, EngineerMate compared different sources and determined the L/D factor for each of them as listed in the following table.

FITTING EQUIVALENT LENGTHS - Building Code Resource Library

Building Code Resource Library 1 May 16, 2010 FITTING EQUIVALENT LENGTHS Pressure losses in fittings are due to the turbulence created as water flows through the fitting. Hence, the pressure losses in fittings are constant for a given flow (Q), regardless of

Pipe Elbow Center Calculation » The Piping Engineering …

For standard degrees of pipe elbows such as 45 and 90 , elbow center to end dimensions are available in standard pipe charts. But many times, custom elbow angles are required at site which should be cut from standard 45 or 90 elbows. Formula for calculating

Equivalent Length - Neutrium

Fittings such as elbows, tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method. The

Equivalent Pipe Length Method - Pressure Loss

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).

Equivalent Length of Pipe Calculator

Compute equivalent length of pipe Units: f and K are unit-less. D and L eq have the same units. For instance: If D is in meters, then L eq is in meters. If D is in inches, then L eq is in inches.
