"Rurociągi DN 100 z każdego toru łączą się w rurociąg DN 200 o długości zastępczej 74 m. Rurociąg ten połączony będzie z rurociągiem oparowym z XXX (45m długości zastępczej DN 45 z każdego toru, 114 m długości zastępczej rurociągu DN200)."
Znalazłem gdzieś "hydraulic length" i "artificial length", ale żadne tu raczej nie pasują. Może "theoretical length"?

equivalent length of pipe
Definition of equivalent length. The resistance of a mine airway obstruction, duct or pipe elbow, valve, damper, orifice, bend, fitting, or other obstruction to flow, expressed in the number of feet of straight airway, duct, or pipe of the same cross section that would have the same resistance.

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 strength of the equivalent length method is that it is very simple to calculate. The weakness of the equivalent length method is that it is not as accurate as other methods unless very detailed tabulated data is available.

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 - http://www.katmarsoftware.com/articles/pipe-fitting-equivale...

Wartość oporu miejscowego zależy od;
liczby Reynoldsa,
chropowatości wewnętrznej,
kształtu elementu wyposażenia instalacji,
rozkładu prędkości w przekroju,
a dla elementów odcinających również od stopnia otwarcia.

----------
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:
the advantages and disadvantages of each method
Reynolds Number and the flow regime (turbulent vs laminar)
the fitting size
the roughness of the fitting
the roughness of the attached piping
converting data from one method to another
