# Minenergo-278. Thermal conductivity terms of pipe insulation materials

Source:`R/m278insdata.R`

`m278insdata.Rd`

Data represent values of terms (intercept and factor) for calculating thermal conductivity of pipe insulation as a linear function of temperature of heat carrier (water). Those values are set for different insulation materials in Appendix 5.3 of Minenergo Method 278 as norms.

## Format

A data frame with 39 rows and 4 variables:

- id
Number of insulation material table 5.1 of Appendix 5.3 in Minenergo Method 278. Type:

`assert_integerish`

.- material
Designation of insulation material more or less similar to those in table 5.1 of Appendix 5.3 in Minenergo Method 278. Type:

`assert_character`

.- lambda
Value for intercept, [

*mW/m/°C*]. Type:`assert_integer`

.- k
Value for factor. Type:

`assert_integer`

.

## Details

Usually the data is not used directly. Instead use function `m278inshcm`
