The resistance values are obtained by computing the hydraulic resistance for each pipe, given by the Hazen-Williams equation.
Using the measured results, the friction factor for each pipe element was calculated and a procedure for transfer rate estimation was developed.
The hydraulic design problem is modeled as a Shortest Path Problem [2], where the underlying graph considers every feasible combination of diameter and slope for each pipe in the series.
This paper proposes auxiliary spheres instead of the initial pipe surfaces as the base surfaces in constructing closings, so that the closing based algorithm of two steps (constructing a closing for each pipe and blending the closings) can G1-continuously connect multiple parametric normal ringed surfaces with freeform directrices and variable radii.
CFBS follows a greedy strategy to compute the minimum t ij for each pipe P ij.
It is difficult and too costly to have parallel pipe for each pipe or even for some critical pipes.

The test specimen consisting of pipe having free length between the end fittings equal to ten times the outside diameter, but not less than 250 mm and not greater than 750 mm, has been taken for testing from each pipe to be tested.
Holes were made in the upper surface of each pipe for the introduction of transplants of Stevia and two small slits were made on each side for drainage or leaching.
We define a local search method that simultaneously looks for the least cost topology of the network and for the optimal diameter of each pipe.
Since the order of the transfer matrix for either each pipe segment or the entire piping system is 4×4, which is independent of the number of the spans for the system, the presented approach is simpler than the existing techniques, particularly for the piping systems with large number of spans.
But together they also provided more leads for the FBI, which mined each pipe bomb for clues at a laboratory in Quantico, Virginia.
