Analytical relations, a Poiseuille network flow model and two finite element Navier-Stokes one-dimensional flow models have been developed and used in this investigation. The comparison highlights the differences between Poiseuille and one-dimensional Navier-Stokes flow models which may have been unjustifiably treated as equivalent in some studies.","authors_text":"Taha Sochi","cross_cats":["q-bio.QM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2013-05-11T21:56:26Z","title":"Comparing Poiseuille with 1D Navier-Stokes Flow in Rigid and Distensible Tubes and Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.2546","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f0d42dc5721306cfaf9c2b2da0e4a3bf95054fbeafde7450b1e35a4808390fe1","target":"record","created_at":"2026-05-18T03:25:57Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"4bc994c81921b1dbbfe9a58aa053d62694d9b4c69b7a124b697a90b9e9b85494","cross_cats_sorted":["q-bio.QM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2013-05-11T21:56:26Z","title_canon_sha256":"402bb16eaf8a26b135824bee10110eebec8641a49588ce4aeb3b764bb11845a3"},"schema_version":"1.0","source":{"id":"1305.2546","kind":"arxiv","version":1}},"canonical_sha256":"42b6adb58d28628749ed8b2b79969843397cca285932401bedf43c282a0c451d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"42b6adb58d28628749ed8b2b79969843397cca285932401bedf43c282a0c451d","first_computed_at":"2026-05-18T03:25:57.570374Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:25:57.570374Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"68r8iA5slYK4z4Tj1/qILGGpGR3/svj3ALqAnfmMVspQxhidkRySwvl7H69+Wp8SCMrB7ytzEPYKHBI62hfNBA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:25:57.570903Z","signed_message":"canonical_sha256_bytes"},"source_id":"1305.2546","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f0d42dc5721306cfaf9c2b2da0e4a3bf95054fbeafde7450b1e35a4808390fe1","sha256:664c60eff335b0e10c2e3764308dfc04bbe5b9a03b8bf0f0d77d9e4254271d8a"],"state_sha256":"cb2103d9c40980b212647aa85e8f47f75791ba813a0ace0dd81ac6a7de498f00"}
