To calculate feed rate, you need to know:

To calculate feed rate, understanding the capacity or flow in million gallons per day (MGD) is essential because it directly provides the volumetric flow rate of the substance being processed. This measurement allows operators to determine how much liquid or material is entering a system over a specific time frame, which is crucial for operations in physical and chemical processing. Knowing the flow rate in MGD enables operators to balance inputs with outputs effectively, ensuring that processes are efficient and meet operational demands.

While other factors like the volume of the vessel, pressure in the waste line, and hydraulic loading rate can provide important context or support calculations, they do not directly dictate the feed rate. The feed rate is fundamentally about how much material is being introduced into the system over time, and MGD is one of the most straightforward metrics for understanding this flow.
