Right-Size Your Hoses and Pipes To Reduce …

Over-sized hose or tube can add cost, size and weight to a system and decrease the rate of flow. To understand what “right-sizing” means in terms of hydraulic hose and tube, you must first understand the nature of fluid and friction. Whenever fluid flows, there is a loss of mechanical energy to overcome viscous forces within the fluid. In a hydraulic system, this loss is seen as a pressure
