RHO_MATERIAL

This function returns the tabulated density of a building, insulation, or refractory material. A direct material ID can be provided, or a search string can be used to resolve the nearest matching material entry.

Density is mass per unit volume:

\rho = \frac{m}{V}

The result is reported in kg/m^3 and is taken as a lookup-table property without temperature dependence.

Excel Usage

=RHO_MATERIAL(ID)

• ID (str, required): Material ID or search term (dimensionless).

Returns (float): Density of the material (kg/m^3).

Example 1: Asbestos cement board density

Inputs:

ID
Board, Asbestos/cement

Excel formula:

=RHO_MATERIAL("Board, Asbestos/cement")

Expected output:

1900

Example 2: Copper density

Inputs:

ID
Metals, copper

Excel formula:

=RHO_MATERIAL("Metals, copper")

Expected output:

8900

Example 3: Soda lime glass density

Inputs:

ID
Glass, soda lime

Excel formula:

=RHO_MATERIAL("Glass, soda lime")

Expected output:

2500

Example 4: Fused silica density

Inputs:

ID
Fused silica

Excel formula:

=RHO_MATERIAL("Fused silica")

Expected output:

1940
