Heat Loss The rate of heat loss (in watts) in harbor seal pups has been approximated by

$H\left(m,T,A\right)=\frac{15.2m^{0.67}\left(T-A\right)}{10.23\ln m-10.74}$,

where $m$ is the body mass of the pup (in kg), and $T$ and $A$ are the body core temperature and ambient water temperature, respectively (in $°\text{C}$). Find the heat loss for the following data. Source: Functional Ecology.

a. $\text{Body mass }=21\text{ kg}$; $\text{body core temperature }=\text{ 36}°\text{C}$; $\text{ambient water temperature}=4°\text{C}$

b. $\text{Body mass }=29\text{ kg}$; $\text{body core temperature }=\text{ 38}°\text{C}$; $\text{ambient water temperature}=16°\text{C}$
