Fluid viscosity, distance required in the application, and other factors affect pressure drop in industrial fluid systems. A new video explains each factor.
This video steps through key factors that influence system pressure drop. We also have a book that goes into detail: The Swagelok Tube Fitters Manual. Edmonton Valve & Fitting is here to help if you have questions: 780-437-0640.
Flow capacity — the amount of fluid that can flow through a hose or tube — isn't just a matter of how large the diameter is. Flow capacity is really a matter or pressure drop. And pressure drop is influenced by four key factors.
Let's start with the fluid itself. How viscous is it? The more viscous, the slower the flow (and vice versa). Next consider pressure and temperature. Some fluids flow differently under pressure and at different temperatures.
Third is the inside surface of the tube or hose. A smooth inner core will mean a smoother flow, while a convoluted core will create turbulence.
Finally, take into account the distance involved in the application. The longer the distance, the more resistance will build up between the fluid and the interior of the tube or hose, which will create additional pressure drop.
