The formula to calculate the Net Explosive Weight (NEW) is:
\[ NEW = DSW \times 0.50 + DCW \times 0.25 \]
Where:
Let's say the weight of display shell cases (\( DSW \)) is 100 lbs and the weight of display cakes and candles (\( DCW \)) is 50 lbs. Using the formula:
\[ NEW = 100 \times 0.50 + 50 \times 0.25 \]
We get:
\[ NEW = 50 + 12.5 = 62.5 \text{ lbs} \]
So, the Net Explosive Weight (\( NEW \)) is 62.5 lbs.
Net Explosive Weight (NEW) is the total weight of explosive material in a firework or other explosive device. It is calculated by considering the weights of different components, such as display shell cases and display cakes and candles, and applying specific factors to each. This measure is important for safety and regulatory purposes in the handling and use of explosives.
