Final answer:
The gallons per minute (GPM) that a 1 1/2" Penberthy siphon ejector can supply varies based on factors such as pressure differential and design specifics. The manufacturer's performance curves or specifications are needed for an exact figure.
Step-by-step explanation:
The 1 1/2" Penberthy siphon ejector is a piece of equipment typically used in industrial applications for transferring fluids. The capacity in terms of gallons per minute (GPM) that a siphon ejector can supply will depend on various factors including the pressure differential and the specific design of the ejector. To determine the exact GPM rate for a 1 1/2" Penberthy siphon ejector, you would need to refer to the manufacturer's performance curves or specifications for that particular model.
The information is likely provided in the product manual or technical datasheets. In the absence of specific data, an estimation can sometimes be made using standard fluid dynamics and pump equations, but for a precise figure, consulting the actual documentation or contacting the manufacturer is always recommended.
