Druckverlust 6.2

Druckverlust is a term used in engineering and fluid dynamics to describe the loss of pressure within a system due to factors such as friction, obstructions, or changes in flow direction.

Understanding and calculating the pressure loss in a system is crucial for designing efficient fluid transportation networks and ensuring optimal performance of equipment like pumps, pipes, and filters.

Druckverlust can be measured using pressure gauges or sensors placed at different points within a system. The difference in pressure between these points is an indicator of the pressure loss experienced by the fluid.

Several factors contribute to Druckverlust, including pipe length, diameter, roughness, flow velocity, fluid viscosity, and the presence of fittings, valves, and bends in the system.

The Darcy-Weisbach equation is commonly used to calculate Druckverlust in a pipe system. It takes into account the pipe characteristics, flow rate, and fluid properties to estimate the pressure loss.

Druckverlust can be reduced by using larger diameter pipes, smoother inner surfaces, avoiding excessive bends or restrictions, minimizing pipe length, and optimizing flow velocities.

High Druckverlust leads to decreased system efficiency, increased energy consumption by pumps or compressors, reduced flow rates, and higher maintenance costs due to excessive wear and tear on equipment.

While it is not possible to completely eliminate Druckverlust, it can be minimized through careful design, regular maintenance, and proper selection of pipe materials and fittings.

Druckverlust refers to pressure loss specifically within a pipe or system, whereas pressure drop is a more general term, also encompassing pressure changes across components like valves, filters, or heat exchangers.

Various industry standards and guidelines exist to estimate and calculate Druckverlust, such as the Hazen-Williams formula for water pipes or the Moody chart for turbulent flow in different pipe materials.
