Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Given Information
- Weight of fire extinguisher: $$10 \text{ lb}
- Discharge rate is not explicitly stated, so we'll need to use a standard discharge rate
Step 3:: Research Standard Discharge Rates
- Typical fire extinguishers discharge at approximately $$0.5 \text{ lb/second}
Step 4:: Calculate Discharge Time
- $$\text{Discharge Time} = \frac{10 \text{ lb}}{0.5 \text{ lb/second}}
- Total time = Total weight ÷ Discharge rate
Step 5:: Perform Calculation
- $$\text{Discharge Time} = 20 \text{ seconds}
Step 6:: Verify Calculation
- $$20 \text{ seconds} \times 0.5 \text{ lb/second} = 10 \text{ lb} \checkmark
Final Answer
Note: Actual discharge time may vary slightly depending on specific extinguisher model and discharge conditions.
