When an evaporated sweat rate of 0.26 litres (kg) per hour corresponds to a heat loss of 100 Wm-2. to maintain heat balance the body would therefore have to produce 0.454 litres of sweat per hour that is
R = 1 - 0.932
2
Sreq = 97.88
0.56
= 174.79 wm-2
= 0.454 litres per hour.
How did they work out it was 0.454 litres per hour?

174.79/100 * 0.26 = 0.454.
And it seems the 174.79 came from 97.88/0.56.
How you/they got the 97.88 and 0.56 from the numerical and formulaic scraps you've provided would be my question. Maybe 97.88 is the heat loss per hour and 0.56 is the area. But I would think that the evaporation rate should be proportional to heat loss, not heat loss/area. How about cleaning up the question?

Your question does not fit into my understanding of ergonomics.
