Characteristics and functions of the program

This calculation program on Excel makes it possible to dimension and carry out the calculation of the pressure losses on the distribution systems of gas. It applies to all the types of pipes and particularly holds account operating conditions and specific characteristics on the pipes, such as:

  • The temperature of the gas conveyed (see: list gas below)
  • The temperature of gas distribution.
  • The pressure of gas distribution.
  • The nature of the various types of materials used (steel pipeline, copper, PVC, built walls, etc.)
  • The different types of local pressure loss.

Complementary modules of calculations are incorporated in the program, has to know:

  • Pipe table editor made up of 246 pipes with 11 categories of piping.
  • K-factor editor of the local pressure loss.
  • Orifice plate calculator.
  • Control valves calculator (Kv, etc.)
  • Equivalent K-factor calculator.
  • Calculator of the motorized power for compressor.

The types of pipes integrated in the AeroGaz program for the calculation of the pressure losses, are:

  • Black iron T1 and T2 pipes (traditional use)
  • Galvanized iron pipes
  • black iron T3 pipes
  • Black iron T10 pipes
  • Coppers pipes (everyday usage)
  • Coppers pipes (refrigerating quality)
  • PVC ground heating pipes
  • PVC pressure pipes
  • Polyethylene pipes (PehD)
  • Polyethylene pipes for gas
  • Stainless 316L pipes

The calculation program is equipped with a command bar personalized giving access to the various procedures, boxes of calculations and macro-commands.

The working files are created separately making it possible to reduce the data storage.

Pressure loss calculation for gas supply. Local head losses. Gas density. Gas specific gravity. Natural gas properties

The type of gas employed can be replaced by another gas during the phase calculation.

Table of the calculation of pressure loss

The working sheet file can be made up of various pipes. You can start from the same file, to insert a new worksheet or to duplicate the worksheet in progress for a similar study and to make the complementary modifications thereafter.

In your table of calculation you can add or withdraw lines of calculation, without deteriorating the phases of calculations.

You can also choose the unit of pressure of your choice in the study:

  • Pa (Pascal)
  • Pounds per square foot (lbf/sq ft) = 47.88026 Pa
  • Torr / mm Hg (133.3226 Pa)
  • kPa ( = 1000 Pa)
  • Feet of water (ft) = 2989.07 Pa
  • Psi (Pound per square inch (lbf/sq. in) = 6894.757 Pa)
  • Bar (100000 Pa)

For each sheet of the table of calculation, the presentation is done, that is to say:

In display basic:

Gas pipes sizing. Pressure loss calculation for gas supply. Local head losses. Gas density. Gas specific gravity

In complete display:

The table visualizes in complement:

  • The roughness factors.
  • The gas density.
  • The gas specific heat.
  • The gas dynamic viscosity.
  • The Reynolds number.

Natural gas properties. Choice of gas. Pipes selection.

All the cells of calculation in purple are programmed.
