Answer:

(a) $fd=1.7058\times 10^{-5}\ L.hr^{-1}.cm(b) [tex]r=26.008\ cm$

Explanation:

(a)

Oxygen consumption rate of humans, $Q_h=14.5\ L.hr^{-1}$

area of human skin, $A_h=1.7\ m^2$

diffusion rate through skin of humans, $d=2\%\ of\ Q_h$

∴ $d=\frac{2}{100} \times 14.5$

$d=0.29\ L.hr^{-1}$

<u>Flux of diffusion rate, </u>

$fd=\frac{d}{A}$

$fd=\frac{0.29}{17000}$

$fd=1.7058\times 10^{-5}\ L.hr^{-1}.cm(b)Surface area for a spherical animal:[tex]A=4.\pi.r^2$

Diffusion flux rate for animal:

$fd=\frac{14.5}{A}$

$1.7058\times 10^{-5}=\frac{14.5}{4.\pi.r^2}$

$r=26.008\ cm$
