Convert heat flux to specific heat loss power

Convert heat flux measured for a cylindrical steel pipe to specific heat loss power of pipe.

Usage

loss_flux(x, d = 720)

flux_loss(x, d = 720)

Arguments

x

value of

• heat flux, [W/m²], for loss_flux(x, d, wth)

• specific heat loss power, [kcal/m/h], for flux_loss(x, d, wth)(x)

Type: assert_double.

d

nominal (outside) diameter of pipe, [mm]. Type: assert_double.

Value

Value of

• specific heat loss power, [kcal/m/h], for loss_flux(x, d, wth)

• heat flux, [W/m²], for flux_loss(x, d, wth)(x)

Type: assert_double.

Examples

library(pipenostics)

# Consider pipes with nominal (outside) diameters:
d <- c(998, 1395)  # [mm]

# Then maximum possible normative neat loss according (Minenergo-325) is
loss_max <- c(218, 1040)  # [kcal/m/h]

# The appropriate flux is
flux <- flux_loss(loss_max, d)
print(flux)
#> [1]  80.86411 275.98722
