.. _section-5.3: Specific Components: Contributions to Flow and Pressure Equations ----------------------------------------------------------------- In this section, we shall consider the contributions to the mass flow-rate and pressure equations from the various components in the primary and intermediate loops. Each compressible volume contributes a :math:`b_0`, a :math:`b_1`, and a :math:`b_2` in :eq:`5.2-19`, and each element in each segment connecting two compressible volumes contributes a :math:`\Delta a_0`, a :math:`\Delta a_1`, a :math:`\Delta a_2`, and a :math:`\Delta a_3` in :eq:`5.2-10`, :eq:`5.2-12`, :eq:`5.2-14`, and :eq:`5.2-16`. We shall consider compressible volumes without cover gas, compressible volumes with cover gas, pipes, intermediate heat exchangers, and pumps. .. toctree:: :maxdepth: 2 hydra-CV hydra-CVwCG hydra-pipe hydra-pump hydra-valve hydra-checkValve
