Hello,
I would be happy to help you with your science project. The suction rate of a gravity type coalescing separator can vary depending on factors such as the size and design of the separator, the viscosity of the fluid being processed, and the temperature of the fluid. Generally, the suction rate can range from 50-500 liters per minute.
As for the processing time, it can also vary depending on the same factors mentioned above. However, on average, it can take anywhere from a few minutes to a few hours for the coalescing separator to fully process the fluid.
I hope this information helps with your project. Let me know if you have any further questions. Best of luck!
