    Calculations

    Straight Pipe
    Calculators for pressure drop by flow through a straight pipe.
    The diameter and wall roughness can be user defined or chosen from a listing of standard pipe sizes.

    Pipe with Fittings
    Calculators for pressure drop by flow through a pipe with fittings.
    The number of fittings can be put in manually or estimated by the calculation routine using a correlation based on complexity and average plant data. Uses the 2-k methode for the pressure drop through the fittings, which is the best available method for both the laminar and turbulent flow.

    Information

    Wall Roughness values
    Tabulation of typical Wall Roughness for several materials in mm.
    The data is useful for User Defined Pipe pressure drop calculations.
