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?
