How much water will a ram deliver?
The amount of water delivered depends on the fall, the elevation to which water is being pumped, and the amount of water entering the ram through the drive pipe. The formula for calculating delivery is: D=VxF/Ex6/10, where D is delivery in gallons per minute, V is the volume of water entering the ram in gallons per minute, F is fall in feet, and E is the elevation the water is being pumped to.
