    Pipe_f.Loss 1.2for Windows PC only

    Featuring

    valves & fittings losses by 2-K Method developed by Hooper.

    4 options (Colebrook, Swamee, etc) for solving friction factor.

    click & select with built-in database, conversion calculator, etc.

    save/open project, save results for printing.

    fully mobile plug-and-use program with no setup requirement.

    System Requirements

    Option to set upper limit of laminarflow regime.

    Turbulent flow equation is used tosolve friction factor for Reynoldsnumber above this limit. Else,laminar flow equation is used.

    Your choice ofmeasurement units:

    English or Metric.

    Save result in rtf file.Save, open existing project.

    Select fluid from database with density& dynamic viscosity properties. Youcan edit the properties value.For greater flexibility, drop-down listincludes option for user defined input.

    Select pipe material from database

    with roughness property. You can editthe property value.For greater flexibility, drop-down listincludes option for user defined input.

    Options (both implicit &explicit method) for

    solving friction factor.

    Darcy formula is usedfor pressure drop

    calculation.

    Example (using 2K method) in IP units

    Consider a 16-in (ID = 15.624-in) Sch 40S stainless steel system. The system contains 100 ft of pipe, 6 long-radius(R/D=1.5) 90

    o elbows, 2 side-outlet tees, 2 gate valves (=0.9) and an exit into a tank. The fluid has dynamic

    viscosity of 1 cP, density of 62.43 lb/ft, and the flow rate is 13.314 ft/s. What is the head loss through this system?
