Averaged over gender and ages, an office worker produces the following rates of heat gain: sensible heat gain of 70 W; latent heat gain of 60 W. a) How is the sensible heat gain carried away – i.e., what heat transfer processes are involved? b) How is the latent heat gain released to the surroundings – i.e., what mechanisms are involved? c) Given the above numbers, in order for the worker to be comfortable, what is the rate of heat dissipated by the body? This is referred to as (Hm – W) in the notes (i.e., Hmetabolic – Work). What assumption does this require?

Question
Averaged over gender and ages, an office worker produces the following rates of heat gain: sensible heat gain of 70 W; latent heat gain of 60 W.
a) How is the sensible heat gain carried away – i.e., what heat transfer processes are involved?
b) How is the latent heat gain released to the surroundings – i.e., what mechanisms are involved?
c) Given the above numbers, in order for the worker to be comfortable, what is the rate of heat dissipated by the body? This is referred to as (Hm – W) in the notes (i.e., Hmetabolic – Work). What assumption does this require?
