Figure 7 shows the comparison of the friction loss
between the theoretical results and the experimental data for the expander with springs in the vane.
With rising energy costs, the friction loss
in the pipe at a given flow rate can affect the long-term cost of the pipeline.
in engines cannot be avoided and accounts for between 15 to 20% of the energy expenditure, depending on the size and configuration of the engine.
understanding friction loss
, flow requirements, material to be pumped, specific gravity, etc.
There is no friction loss
due to the weight of the plunger on the bearings robbing the design of valuable force.
5-L gas engine that instead ensures maximum efficiency by reducing friction loss
A precise analysis of the mechanical losses of the engine as also the assessment of possible improvement potentials based on this analysis require an exact metrological registration of the friction loss
Li and Yang  adopted the finite element method to study the static and transient static temperature field distribution of the pressure level panel ultrasonic motor, where mechanical vibration and friction loss
were calculated, and the influence of the high temperature was analyzed by the equivalent insulation, but it lacked the analysis of load influence on temperature field.

The free ESP-System Syzer includes a calculator for friction loss
and velocity through pipe, based on fluid conditions.
The FireLock NXT device line also eliminated the air-to-water differential, allowing faster delivery of water to sprinklers and controlling friction loss
on high-rise installations, ensuring maximum efficiency within the fire protection system from day one.
By combining the dynamic mechanical analysis and the refrigerant pressure analysis of the expansion chamber with leakage analysis, friction loss
of each component of the expander; mechanical efficiency; and volumetric efficiency, which represents expander performance, can be calculated.
