It sounds like a pump card shows the same graph, but you subtract all of the rod weight from data on the dynagraph. At that point, you're evaluating what the force is supposed to be at the pull rod alone. I'd appreciate if someone out there could confirm/clarify this!
Excellent! Thank you!
Dynagraph and pump card are the same thing .? if not then what is pump card , could you please explain .?
