Engineers are working to minimize friction loss in the system.
Инженеры работают над минимизацией потерь на трение в системе.
Definitions
Friction loss refers to the reduction in pressure or flow rate of a fluid as it moves through a pipe or duct due to the resistance caused by the internal surface of the pipe. This loss is influenced by factors such as the fluid's velocity, viscosity, the roughness of the pipe's interior surface, and the length and diameter of the pipe.
