Pressure loss calculation

Individual calculations for pipes, partial resistances, geodetic height and energy balance for compressible and incompressible fluids.

• Enhanced flow resistance database according to I. E. ldel'chik “HANDBOOK OF HYDRAULIC RESISTANCE“
• Graphical support

Support of two-phase flow conditions according to three different calculation methods:

• L. Friedel “Improved friction pressure drop correlation for horizontal and vertical two phase pipe flows” European two phase flow group meeting, Ispra, 5-8 June 1979
• H. Müller-Steinhagen – K. Heck „A Simple Friction Pressure Drop Correlation for Two-Phase Flow in Pipes” Chem. Eng. Process., 20 (1986) 291-308
• Homogeneous flow model

Pressure surge

• Calculation for single-run piping systems which end with a control valve, as a function of the closing time and the valve characteristic
• Valve database and graphical support

Sizing

• Calculation of basic values, such as the surface area, volume, flow velocity and Joukowsky peak

Pipe wall thicknesses

• Calculations optionally according to:

  EN 13480:2002
  DIN 2413:1993
  DIN 2413:1972

• Pipe bends with or without a constant wall thickness can be calculated for pulsating and static loads in addition to straight pipes
• Pipe materials in accordance with EN 13480:2002 can be selected from a user extensible Material Database and you can also calculate all relevant parameters, such as tensile strength, creep rupture strength and yield strength.

Pipe compensation

• Calculations for L and U-bends, changes in length, pipe support loads and stress limits

Span calculation

• Calculation of the individual weights (pipe, medium, insulation)
• Span calculation taking account of sag
• Pipe materials in accordance with EN 13480:2002 can be selected from a user extensible Material Database
