The formula to calculate the KW to Weight Ratio is:
\[ \text{KWR} = \frac{P}{W} \]
Where:
The KW to Weight Ratio is a measure used to assess the power efficiency of a vehicle or machinery. It represents the amount of power (in kilowatts) available per unit of weight (in pounds). A higher ratio indicates better performance and acceleration capabilities relative to the weight of the vehicle or machinery. This metric is crucial for understanding how effectively the power output translates into performance.
Consider the following example:
Using the formula:
\[ \text{KWR} = \frac{250}{5000} = 0.05 \text{ kW/lb} \]
This means the KW to Weight Ratio for this example is 0.05 kW/lb.
