El cuerpo de una persona está cubierto con 1.6 m2 de ropa de lana. El grosor de la lana es 2.0 x 10-3 metro. La temperatura en l
netineya [11]

Answer:

<h2>Rate of heat transfer from the body of the person is given as</h2><h2>\frac{dQ}{dt} = 800 J/s</h2>

Explanation:

As we know that the rate of heat transfer due to thermal conduction is given as

\frac{dQ}{dt} = \frac{kA(T_2 - T_1)}{x}

so we have

k = 0.04 W/m C

A = 1.6 m^2

x = 2\times 10^{-3} m

\frac{dQ}{dt} = \frac{(0.04)(1.6)(36 - 11)}{2 \times 10^{-3}}

\frac{dQ}{dt} = 800 J/s
