Final answer:
The required volume of an equalization basin can be calculated using the equation Q = Av and considering the peak daily flow rate, which is 2.2 times the average flow rate, plus an additional 25% contingency. Unequalized and equalized hydraulic loadings are plotted based on calculated hourly flows and the added volume for equalization.
Step-by-step explanation:
When designing an equalization basin for a wastewater treatment plant, we consider variable inflows and strive to achieve a uniform outflow. The volume of the basin is particularly important to ensure that the system can handle peak flow rates and maintain a consistent discharge rate. The relationship between flow rate and velocity is expressed by the equation Q = Av, where A is the cross-sectional area of the flow and v is the average velocity. This equation indicates that flow rate is directly proportional to both the speed of the fluid and the size of the conduit.
To calculate the required volume for an equalization basin, you must consider the peak daily flow rate, which is 2.2 times the average daily flow rate. This peak flow must be accommodated in the basin while maintaining an outflow rate equal to the average daily flow. Additionally, as a contingency, an extra 25% is added to the estimated volume. To plot the unequalized and equalized hourly hydraulic loadings for the maximum day, you would first compute the hourly flows and then apply the necessary volume adjustments for equalization.
Considering the equations provided, the ratio of peak to average, minimum to average, and peak to minimum hydraulic loading can be determined after establishing the equalized flow rates. Such calculations require an understanding of fluid mechanics and hydraulic engineering principles.
