Pressure drop in piping systems is a critical factor that influences the design, efficiency, and operational integrity of fluid transport systems. It refers to the reduction in pressure as fluid flows through pipes and is primarily caused by friction between the fluid and the pipe walls, as well as other resistive forces. The interaction of flow rate, flow regime, rheological properties, and conduit geometry significantly influences frictional effects in the drill string inner diameter (ID) and annulus. Each of these parameters plays a crucial role in determining the behavior of fluids within drilling systems, affecting efficiency and safety. API RECOMMENDED PRACTICE 13D (SIXTH EDITION, MAY 2010) is used to calculate pressure drop. Example. Read More.
