Using the example values WB = 90, GT = 98, DB = 94, which term contributes 63 to the WBGT total?

Using the example values WB = 90, GT = 98, DB = 94, which term contributes 63 to the WBGT total?

• A. 0.7WB
• B. 0.2GT
• C. 0.1DB
• D. 0.3GT

Answer: (A)

The WBGT is calculated as a weighted sum of three measurements, with the wet-bulb value carrying the largest weight (0.7), followed by the globe value (0.2) and the dry-bulb value (0.1). This means each term’s contribution to the total is its value times its weight. Compute each contribution: - 0.7 × 90 = 63 - 0.2 × 98 = 19.6 - 0.1 × 94 = 9.4 So the term that contributes 63 to the WBGT total is the 0.7 times the wet-bulb value term. The total WBGT would be 63 + 19.6 + 9.4 = 92.

The WBGT is calculated as a weighted sum of three measurements, with the wet-bulb value carrying the largest weight (0.7), followed by the globe value (0.2) and the dry-bulb value (0.1). This means each term’s contribution to the total is its value times its weight.

Compute each contribution:

• 0.7 × 90 = 63

• 0.2 × 98 = 19.6

• 0.1 × 94 = 9.4

So the term that contributes 63 to the WBGT total is the 0.7 times the wet-bulb value term. The total WBGT would be 63 + 19.6 + 9.4 = 92.
