某勞工在WB=30℃,GT=40℃之場所工作,且每小時工作30分鐘,休息30分鐘,今知其一小時之WBGTTWA為31.1℃,求該勞工休息之WBGT值。解:(1)公式WBGT=WBGT(work)×T1(work)+WBGT(rest)×T2(rest)/T1(work)+T2(rest)(2)計算過程31.1=(0.7×30+0.3×40)×30+WBGT(rest)×30/(30+30)WBGT(rest)=(60×31.1)-(33×30)/30=29.2℃【休息時之WBGT】請問:(1)上面ㄉ公式為何跟下面計算過程不同(2)此一計算過程是否有錯(/30=29.2℃)中ㄉ/30代表何值(3)如以您ㄉ角度來回答
