NAsolid

 

The procedure NAsolid provides properties of solid sodium.

 

Call NAsolid(T: rho_e, rho, k, c)

 

Inputs:

T: Temperature 

 

Outputs:

rho_e: electrical resistivity

rho: density

k: thermal conductivity

c: specific heat capacity

 

Note that the procedure operates in whatever unit system EES is set to.  The properties come from the NAPROP procedure listed in Sodium-NaK Engineering Handbook, Volume 1.

 

Example:

 

$UnitSystem SI Mass kJ C kPa

T = 50 [C]

Call nasolid(T: rho_e, rho, k, c)

 

{Solution: rho_e = 5.31e-8 [ohm-m], rho = 962.1 [kg/m^3], k = 127.2 [W/m-K], c = 1.258 [kJ/kg-K]}
