Problem Statement

PRODUCT: AFT Arrow

MODEL FILE: AroVerify10.ARO

REFERENCE: Michael R. Lindeburg, P.E., Mechanical Engineering Review Manual, Seventh Edition, Professional Publications, Belmont, CA, 1984, Pages 8-12, 8-13, example 8.13b

GAS: Methane

ASSUMPTIONS: 1) Isothermal flow, 2) Perfect gas

RESULTS:

DISCUSSION:

The predictions agree closely. Part "a" makes a comparison to the Bernoulli equation, which Arrow does not solve. So part “a” was skipped.

Note that the friction factor in Lindeburg is the Fanning friction factor. To obtain the Darcy-Weisbach friction factor used in AFT Arrow, multiply the Fanning friction factor by 4.
