The formula to calculate the Power Density (Dp) is:
\[ Dp = \frac{P}{L \times W} \]
Where:
Let's say the total power (P) is 1000 watts, the total length (L) is 50 feet, and the total width (W) is 20 feet. Using the formula:
\[ Dp = \frac{1000}{50 \times 20} = \frac{1000}{1000} = 1 \text{ W/ft²} \]
So, the power density is 1 W/ft².
