**Calculating the Required Cross-sectional Area of a Grit Chamber**
To determine the required cross-sectional area of a grit chamber for a given flow rate, we need to consider the population served by the sewage treatment plant and the velocity of flow.
**Step 1: Determine the Design Flow Rate**
In this case, we are given that the population of the city is between 30,000 and 50,000. To estimate the design flow rate, we can use a conservative estimate of 200 liters per capita per day (LPCD). Assuming an average population of 40,000, the design flow rate can be calculated as follows:
Design flow rate = Average population * LPCD * Conversion factor
Design flow rate = 40,000 * 200 * 0.001
Design flow rate = 8,000 m³/day
**Step 2: Determine the Flow Velocity**
The flow velocity is given as 4.5 m/s.
**Step 3: Calculate the Required Cross-sectional Area**
The required cross-sectional area can be calculated using the formula:
Area = Flow rate / Velocity
Area = 8,000 m³/day / (4.5 m/s * 24 hours * 3600 seconds/hour)
Area = 9.26 m²
**Step 4: Select the Closest Option**
Given the options provided, the closest answer to 9.26 m² is 8.3 m² (option 1).
**Conclusion**
Based on the given population and flow velocity, the required cross-sectional area of the grit chamber is approximately 9.26 m². Since this value is closest to 8.3 m², the correct answer is option 1.
