Wet Bulb Globe Temperature (WBGT) is a heat stress index that combines air temperature, humidity, solar radiation, and wind speed to estimate the discomfort level for workers or individuals exposed to hot environments. It is measured using a wet bulb thermometer placed inside a globe thermometer, which simulates human skin's exposure to environmental factors. A lower WBGT value indicates less heat stress on the body.

Question - Chemical Engineering Material - In crystal material, hexagonal crystal system could form 4-digit index in certain direction of solid. For [1(-1)0] direction in the hexagonal crystal systems of particular catalyst applied in fume removal of incinerator, what is the four-digit index for this direction? Hint : The transformation equations between the 3-digit [h’k’l’] and the 4-digit [hkil] indices are : h = (1/3) (2h’ – k’); i = - (h + k); k = (1/3) (2k’ – h’); l = l’. A. [(-1)100] B. [1(-1)00] C. [(-1)000] D. [00(-1)(-1)] E. [(-1)0(-1)0]
