Question

The surface area of a person is 1.9m² and the skin temperature is 31°C. What are the rates of heat transfer through the skin when there is almost no blood flow to the skin and when there is maximum blood flow to the skin?

Answer 1

Gives

Area=1.9m²

Temperature (T)=31°C

Room temperature 26°C

Convective heat transfer (h)=50W/m²°C

We know that

$W=hA(T-T_0)$

the rates of heat transfer through the skin

$W=50\times1.9\times(31-26)$

W=475w
