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.
