Answer:
Rate of Heat Loss = 336 W
Step-by-step explanation:
First, we will find the surface area of the cylinder that is modelled as the man:
where,
r = radius of cylinder = 30 cm/2 = 15 cm = 0.15 m
l = length of cylinder = 170 cm = 1.7 m
Therefore,
Now, we will calculate the rate of heat loss:
where,
h = convective heat tranfer coefficient = 15 W/m²K
ΔT = Temperature difference = 34°C - 20°C = 14°C
Therefore,
Rate of Heat Loss = 336 W
