(a) A 70-kg person at rest has an oxygen consumption rate Qhum = 14.5 liter/h, 2% of which is supplied by diffusion through the

nevsk [136]

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:

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

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

$r=26.008\ cm$

What is 10^2 in scientific notation?

Eduardwww [97]

Answer:

1×10^2

Explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
