What Is Friction Loss?

If you do not know what your friction loss is, it is very difficult to come up with the final term or final pressure in relationship to the pump application.  Friction loss is defined as the total drag on the fluid on the pipe of the fluid that you are pumping.  For example, if we are in a salt water application and we are pumping fluid 3/4’s of a mile to a tank battery through a 2- inch line, then friction loss is going to be a lot greater than if we are pumping something that is very light specific to gravity or viscosity, such as gasoline 20 feet in the air. The friction loss on that pipe is going to dictate how much pressure that is initially required to get the fluid where it needs to go.

Another factor that has a huge effect on this is radio loads. Radio loads, diameter of the pipe, the elbows, values, small orifice plates, and relief valves and all play into how much friction loss ultimately we are going to have to have, which is basically pressure.
