HydraulicResistance 1.0.11-alpha

Hydraulic Resistance

GitHub repository https://github.com/jeisonjei/HydraulicResistance
Library for calculations of fittings's hydraulic resistance based on "Handbook of Hydraulic Resistance" I.E.Idel'chik. This is alpha version of library so use with caution

Arguments

equivalentRoughnessMillimeter - 0.1 mm for ducts and 0.2 mm for water heating pipes can be used. Detailed table for different types of pipes can be found at https://ccjx.space/handbook/Эквивалентная-шероховатость-труб-и-каналов - page on russian but can be translated using browser tools.
tempCels - air or water temperature in degrees Celsius.

Rest of arguments should be self-explained

Elbows

Depending on shape use ElbowRound or ElbowRectangular:

double roundElbowResistance=ElbowRound.Resistance(...arguments...);

Tees

Depending on flow direction and shape use appropriate classes. Methods .OnPassResistance() means main passage resistance and .ToTurnResistance() means branch passage resistance

double supplyTeeRectangularBranchResistance=TeeSupplyRectangular.ToTurnResistance(...arguments...);

Diffusers

To calculate conical diffuser's resistance:

double conicalDiffuserResistance=DiffuserConical.Resistance(...arguments...)

To calculate pyramidal diffuser's resistance:

double pyramidalDiffuserResistance=DiffuserPyramidal.Resistance(...arguments...)

To calculate flat diffuser's resistance:

double flatDiffuserResistance=DiffuserFlat.Resistance(...arguments...)

Confusers

To calculate conical confuser's resistance:

double conicalConfuserResistance=ConfuserConical.Resistance(...arguments...)

To calculate pyramidal confuser's resistance:

double pyramidalConfuserResistance=ConfuserPyramidal.Resistance(...arguments...)

To calculate flat confuser's resistance:

double flatConfuserResistance=ConfuserFlat.Resistance(...arguments...);

Velocity, Reinolds number and Lambda

To get velocity:

var flow=new Flow(...arguments...);
var velocity=flow.GetFlowVelocity(...arguments...);

To get Lambda:

var flow=new Flow(...arguments...);
var lambda=flow.GetLambda(...arguments...);

Attention

Calculations has not been carefully checked yet. Seems like results are close to truth, but test against results from handbook are necessary
