Secant coefficient of thermal expansion
Did you know?
When calculating thermal expansion it is necessary to consider whether the body is free to expand or is constrained. If the body is free to expand, the expansion or strain resulting from an increase in temperature can be simply calculated by using the applicable coefficient of thermal expansion. If the body is constrained so that it cannot expand, then internal stress will be … Web11 Apr 2024 · Finally, DOE notes that use of the OCMG concept for CRACs is consistent with the approach finalized by DOE in test procedure final rules for direct expansion-dedicated outdoor air systems ( see87 FR 45164 (July 27, 2024)) and single package vertical units ( see87 FR 75144 (Dec. 7, 2024), and proposed in a test procedure NOPR for water-source …
