  • How It Works: Pressure Loss Schlumberger

    Pressure loss that occurs along the direction of flow in a pipe is caused by fluid friction—both internal in the fluid itself and with the piping surfaces—piping restrictions, or sudden changes in the geometry of the flow path. Thus, pressure loss is directly related to fluid velocity, specific gravity, viscosity, and the pipe
