recordNormalDensities

Record containing densities at STP (T=273.15 K, p=1.01325 bar) for components of natural gas in kg/m3

Extends from TransiEnt.Basics.Icons.Record (Icon for records).

Information

1. Purpose of model

This record contains densities at STP for some gas components used in the TransiEnt library.

2. Level of detail, physical effects considered, and physical insight

No physical effects considered.

3. Limits of validity

(no remarks)

4. Interfaces

(no remarks)

5. Nomenclature

(no elements)

6. Governing Equations

The names vector contains the component names

.

In the normal densities vector the densities for each component is defined in kg/m3

7. Remarks for Usage

Be sure to store the densities for each component in rho_n vector in the same column in which the name is stored in the names vector.

8. Validation

No validation needed.
