Qconduction_substrate {TrenchR}

Conductance Assuming Substrate Thermal Conductivity is Rate Limiting

Description

The function calculates conductance (W) of an ectothermic animal to its substrate. The method assumes the major resistance to conduction is the substrate and that the interior of the animal is equal in temperature to its surface (thermally well mixed) (Spotila et al. 1992).

Usage

Qconduction_substrate(T_g, T_b, D, K_g = 0.5, A, proportion)

Arguments

T_g

numeric surface temperature (K).

T_b

numeric body temperature (K).

D

numeric characteristic dimension of the animal (m).

K_g

numeric thermal conductivity of substrate (W K^-1 m^-1).

A

numeric surface area (m²).

proportion

numeric proportion in contact to the surface.

Value

numeric conductance (W).
