Qevaporation: Heat Loss Associated with Evaporative Water Loss

In TrenchR: Tools for Microclimate and Biophysical Ecology

Heat Loss Associated with Evaporative Water Loss

Description

The function estimates heat loss associated with evaporative water loss for an amphibian \insertCiteSpotila1992TrenchR or lizard. The lizard estimation is based on empirical measurements in \insertCitePorter1973;textualTrenchR).

Usage

Qevaporation(A, T_b, taxon, e_s = NA, e_a = NA, hp = NA, H = NA, r_i = NA)

Arguments

A	numeric surface area (m2).
T_b	numeric body temperature (K).
taxon	character organism type. Current choices: "lizard", "amphibian_wetskin" (fully wet skin), "amphibian" (not fully wet skin).
e_s	numeric saturation water vapor density at skin surface (kg m-3) (needed if amphibian).
e_a	numeric saturation water vapor density in ambient air (kg m-3) (needed if amphibian).
hp	numeric relative humidity (0-1) (needed if amphibian).
H	numeric convective heat transfer coefficient (W m-2 K-1) (needed if amphibian).
r_i	numeric internal (cutaneous) resistance to vapor transport (s m-1) (needed if amphibian).

Value

numeric evaporative heat loss (W).
